Chapter 1 Command Introduction

iv. Input a question mark after a command, a keyword or a parameter, the next keyword or parameter to be input will be listed, and also a brief explanation will be given. Note that a space must be entered before the question mark. 2. If incorrect command, keyword or parameter is input, the error isolation is offered with ^ in the user interface after you press ENTER. The ^ is below the first character of the input incorrect command, keyword or parameter. 3. ZXR10 router/Ethernet switch allows the command or keyword to be abbreviated into a character or character string that uniquely identifies this command or keyword. For example, the show command can be abbreviated to sh or sho. 4. The user interface supports the function of recording input commands. A maximum of ten history commands can be recorded. The function is very useful in re-invocation of a long or complicated command or ingress. To re-invoke a command from the record buffer, conduct one of the following operations, as shown below. Command

Function

Press CTRL-P or the up arrow key

Re-invokes the latest command in the record buffer. Repeat these keys to invoke old commands forwards.

Press CTRL-N or the down arrow key

Rolls the commands downward. When the last command line is reached, one more operation will roll the commands from the begging of the buffer cyclically.

In any mode, execute the show history command to list the latest commands input in this mode.

clear mpls ldp Purpose Command Modes Syntax Syntax Description

Instructions

Example

Use this command to reset the LDP router or its connection with some neighbor. Privileged EXEC clear mpls ldp [neighbor ] neighbor

IP address of the neighbor, in the dotted decimal format

After this command is configured, the router is reset and interrupted, and all LDP sessions are reestablished. The recheck of the access-fec and egress policies, advertisement and request policies, and the explicit pop-up label advertisement policy is performed on all FECS. The resetting of the session with the designated neighbor means the interruption and the reestablishment of the LDP session with this neighbor only. The recheck is only performed on the policy related with this neighbor (advertisement, request, and exp-null policies). �

This example describes how to reset LDP. ZXR10#clear mpls ldp

�

This example describes how to reset the session with the LSR whose router ID is 100.1.1.1. ZXR10#clear mpls ldp neighbor 100.1.1.1

clear mpls ldp dampening Purpose Command Modes Syntax Syntax Description

Instructions

Example

Use this command to clear LDP routes dampening and unsuppress the suppressed routes. Privileged EXEC clear mpls ldp dampening []

The network IP address relates to clear damp information, in the dotted decimal notation

Network mask, in the dotted decimal notation

After this command is configured, the router will clear and reset LDP dampening information already generated, and the router will unsuppress the suppressed LSP; the router will reset flapping suppress information of some specified LSP, and only the dampening information of this LSP will be cleared. If this LSP is suppressed, the router will unsuppress it. �

This example describes how to reset LDP dampening information.

ZXR10#clear mpls ldp dampening

Chapter 2 MPLS LDP Configuration

�

This example describes how to reset dampening information of a LSP.

ZXR10#clear mpls ldp dampening

clear mpls ldp flap Purpose Command Modes Syntax Syntax Description

Instructions

Example

Use this command to clear the flapping statistic information of LDP routers. Privileged EXEC clear mpls ldp flap []

Network IP address, in the dotted decimal format

Network mask, in the dotted decimal format

After this command is configured, the router will clear the count of the flapping of LDP entities where flapping has already occurred , and the router will reset the count of the flapping of some specified LSP; only the count of the flapping of this LSP is cleared and reset and it will be recounted from 0. �

This example describes how to rest LDP flapping statistic information. ZXR10#clear mpls ldp flap

�

This example describes how to reset the flapping statistic information of a LSP. ZXR10#clear mpls ldp flap 100.1.1.1 32

mpls ip (Global Configuration) Purpose

Command Modes Syntax

Use this command to enable LDP to establish an LSP along a common hop-by-hop routing path. Disable LDP with the no form of this command. Global configuration mpls ip no mpls ip

Defaults Instructions

LDP is disabled by default. �

his command enables LDP to establish an LSP along a common hop-by-hop routing path. In addition, it is necessary to enable LDP on the interface to realize dynamic label switching on the interface.


9


�

Use the no form of this command to disable LDP to establish an LSP along a common hop-by-hop routing path no matter whether LDP is enabled on the interface or not.

mpls ip(Interface Configuration) Purpose Command Modes Syntax

Use this command to enable LDP label switching on the interface. Disable LDP label switching with the no form of this command. Interface configuration mpls ip no mpls ip


Example

This command is disabled by default. �

This command enables LDP to exchange labels on the interface of layer 3. Once the command is configured, LSR starts to periodically send hello messages on the interface. When packets to the destination network obtain the outgoing label to some destination network, the outgoing label will be added into the packets and the packets will be forwarded from this interface. Note that this command will take effect only after mpls ip is configured in global configuration mode.

�

The no form of this command make packets routed from this interface no more carry labels and cease the label switching on the interface.

This example describes how to enable LDP on the interface fei_1/1. ZXR10(config)#mpls ip ZXR10(config)#interface fei_1/1 ZXR10(config-if)#mpls ip

Related Commands

show mpls interface show mpls ldp discovery

mpls label range Purpose Command Modes Syntax

Use this command to configure a label range for LDP. Restore default with the no form of this command. Global configuration mpls label range no mpls label range

Syntax Description

10

Minimal available label, range: 16~1048575

Maximal available label, range: 16~1048575



Example

This example describes how to set the label range as 1000~10000. ZXR10(config)#mpls label range 1000 10000

Related Commands

show mpls label range

mpls ldp access-fec Purpose


Use this command to control LDP’s creation of FEC for which destination networks and make sure whether FEC can be created for routing networks obtained by BGP; this command controls FEC filter policy. To disable this feature, use the no form of this command. Global configuration mpls ldp access-fec {for | host-route-o nly | bgp | force} no mpls ldp access-fec [bgp]

Syntax Description


for

Destination network to be filtered, basic ACL: 1~99 and 1000~1499

host-route-only

Creates FEC only for the destination network (host address) with 32-bit mask

bgp

Creates FEC for the specified route network obtained from BGP

force

Takes effect immediatedly

LDP creates FEC for all destination networks except the route networks obtained by BGP. �

By default, LDP creates FEC for all destination networks except the route networks obtained by BGP. However, the number of networks may be so large that it needs to filter the network for which FEC need not be created ; or the network administrator wants to control the creation of FEC , that is, FEC is created only for the authorized network. This command can realize such functions.

�

The mpls ldp access-fec for command can make filter be based on access list. FEC can be created for all destination addresses allowed by the access list. Only standard ACL is supported now.

�

The mpls ldp access-fec host-route-only command make FEC be created only for the destination address with 32-bit mask. The mpls ldp access-fec host-route-only command is especially valid in the MPLS/BGP VPN application, because under such application, LDP only exchanges the label of the next-hop address (that is, the outer label, the label to the PE) of VPN routes. The mpls ldp access-fec host-route-only command can effectively decrease the number of FECs.

�

This command does not collide with the above two policies. By default, FEC is not created for route networks obtained by


11


BGP. This command can make FEC also be created for route networks obtained by BGP. �

Use the mpls ldp access-fec command to configure policy but it does not take effect immediately. But The mpls ldp acce ss-fec force command makes the configuration take effect immediately.

Tip: mpls ldp access-fec for and mpls ldp acce ss-fec host-route-only are mutually exclusive. Thus the network administrator can choose only one control policy at any time.

Example

1. This example describes how to configure the router to create FEC only for the destination address with 32-bit mask: ZXR10(config)#mpls ldp access-fec host-route-only

2. This example describes how to configure the router to create the labels of networks 10.101.0.0 and 10.221.0.0 only and they act immediately. ZXR10(config)#ip access-list standard 10 ZXR10(config-std-nacl)#permit 10.101.0.0 0.0.255.255 ZXR10(config-std-nacl)#permit 10.221.0.0 0.0.255.255 ZXR10(config-std-nacl)#exit ZXR10(config)#mpls ldp access-fec for 10

3. This example describes how to configure the router to create FEC for route networks obtained by BGP. ZXR10(config)#mpls ldp access-fec bgp

mpls ldp advertise-labels Purpose


Use this command to control the distribution of locally assigned labels (incoming labels) through LDP. This command controls which destination network segment labels are advertised to which neighbors. To disable this feature, use the no form of this command. Global configuration mpls ldp advertise-labels [for [to ]] no mpls ldp advertise-labels [for [to ]]

Syntax Description

12

for

Destination network label to be advertised, basic ACL: 1~99 and 1000~1499

to

Advertises which labels to which neighbors, basic ACL: 1~99 and 1000~1499




All labels are advertised to all neighbors by default. The no mpls ldp advertise-labels command without any optional parameter forbids the distribution of any locally assigned labels. To restore the distribution of all locally assigned labels, use the mpls ldp advertise-labels command without any optional parameter. Only standard ACL is supported now. Up to 99 mpls ldp advertise-labels commands can be executed, those commands work together to determine how LSR advertises local labels. In the case that multiple commands are configured, the following rules should be followed: 1. Each mpls ldp advertise-labels command has a (prefix acl, peer acl) pair. The access list pair is (none, none) when no optional parameter is specified; and it is (prefix-acl, none) when the optional parameter is specified but without the keyword no. 2. There is only one (prefix acl, peer acl) pair “applied to” each prefix in accordance with the following rules: i. One (prefix acl, peer acl) pair “applies to” one prefix only when prefix acl “matches” the prefix, and the match condition is that prefix acl permits the prefix. ii.

In the case that there is more than one (prefix acl, peer acl) pair “matching” a prefix; the first (prefix acl, peer acl) pair “applies to” the prefix (in the sequence configured in show running-config).

3. When LSR is to advertise a prefix label, it executes the following operations: i. Finds the (prefix acl, peer acl) pair “applied to” the prefix. ii.

In the case that there is no (prefix acl, peer acl) pair “applied to” the prefix, the label is not advertised to any neighbor if the no mpls ldp advertise-labels command is executed; otherwise, the label is advertised to all neighbors.

iii. In the case that one (prefix acl, peer acl) pair “applied to” the prefix, the label is not advertised to any neighbor if prefix acl denies the prefix. iv. If prefix acl permits the prefix and there is no peer acl (namely none), the label is advertised to all neighbors. v. If prefix acl permits the prefix and there is one peer acl, the label is advertised to all neighbors permitted by peer acl.

Tip: This command takes effect immediately after its configuration. The command can be configured only when the network in stable status. Otherwidse, it could not take effect immediately. Do not use this command frequently.

mpls ldp advertise-labels old-style

mpls ldp advertise-labels old-style Purpose


Use this command to allow the argument after the keyword for in the mpls ldp advertise-labels command to be interpreted according to the earlier Cisco IOS software releases. To disable this feature, use the no form of this command. Global configuration mpls ldp advertise-labels old-style no mpls ldp advertise-labels old-style

Defaults

By default, ZXR10 interprets the parameter after the keyword for according to the rule described in the instruction of the mpls ldp advertise-labels command.

Instructions

Generally, the parameter after the keyword for conforms to the following rules: One (prefix acl, peer acl) pair “applies to” a prefix only when the prefix ACL “matches” the prefix, and the match condition is that the prefix ACL permits the prefix. This is the general processing method of access list. In the early Cisco IOS version, however, the parameter after the keyword for in the mpls ldp advertise-labels command is interpreted in a different way as follows: One (prefix acl, peer acl) pair “applies to” a prefix only when the prefix ACL “matches” the prefix, and the match condition is that

14



prefix ACL permits or denies the prefix explicitly. The parameter prefix ACL with “permit any” or “deny any” matches all prefixes. The difference between the Cisco early rules and the general processing method of access list is that: The explicit deny (including deny any) makes the (prefix acl, peer acl) pair “applied to” the prefix, while the implicit deny does not take any effect. If users are used to the early rule, the mpls ldp advertise-labels old-style command can be used. Example

This example describes how to configure the router to use the early rules of Cisco to interpret the parameter after the keyword for in the mpls ldp advertise-labels command. ZXR10(config)#mpls ldp advertise-labels old-style

mpls ldp backoff Purpose


Use this command to configure the parameter of the LDP session backoff reestablishment mechanism. To restore default, use the no form of this command. Global configuration mpls ldp backoff no mpls ldp backoff

Syntax Description

Instructions

Example

Initial backoff time in seconds, range: 10~65535, default: 15 seconds

Maximum backoff time in seconds, range: 10~65535, default: 120 seconds

�

The LDP session backoff reestablishment mechanism prevents two LSRs with incompatible configurations falling into the endless cycle form the establishment of the session to the failure. If the establishment of the session fails because of the incompatible configurations of the two LSRs, the two LSRs will put off their attempt to establish a session next time (namely back off). The backoff time is exponentially increased until it reaches the maximum backoff.

�

The default value of the parameter of the LDP session backoff reestablishment mechanism is defined by the LDP protocol specifications. There is no need to change tyhe default configuration until the default parameter indeed causes bad behaviors.

This example describes how to set the initial backoff time as 30 seconds and the maximum backoff time as 240 seconds. ZXR10(config)#mpls ldp backoff 30 240

mpls ldp dampening Purpose


Use this command to configure LDP to enable the route dampening or modify the various LDP route dampening factors. Disable this command by using no form of this command. Global configuration mpls ldp dampening [] no mpls ldp dampening

16



Syntax Description


Example

Time (in minutes) after which a penalty is decreased by half after the half-life period (which is 15 minutes by default). The range of the half-life period is 1~45 minutes

Reuse values based on accumulated penalties. If the penalty for a flapping route decrease enough to fall below this value, the route is unsuppressed. range: 1~20000, default: 750

A route is suppressed when its penalty exceeds this limit. range: 1~20000, default: 2000

Maximum time (in minutes) a route can be suppressed. range: 1~255, default: 60 minutes

This command is disabled by default. If there is no parameter after this command, the LDP route dampening will be valid with default values. The parameters have to be configured together.

mpls ldp discovery transport-address Purpose


Use this command to configure the transmission address parameter carried in hello messages on the layer 3 interface. To disable this feature, use the no form of this command. Interface configuration mpls ldp discovery transport-address {interface |} no mpls ldp discovery transport-address


19


Syntax Description

interface

Specifies the interface address as the transmission address advertised in the hello message

Specifies some address as the transmission address advertised in the hello message

Defaults

By default, ZXR10 takes the router identifier as the transmission address advertised in the hello message on the frame interface.

Instructions

A TCP connection must be established before an LDP session is set up between LDP routers, which requires every router know the peer transmission address (IP address). The LDP discovery mechanism enables the LDP router to advertise its own transmission address used for establishing TCP connection to the peer. The advertisement of the transmission address can be explicit (that is, the transmission address appears in the hello message) or implicit (that is, there is no transmission address appearing in the hello message). The receiver of hello messages takes the source IP address of the hello message as the transmission address to set up TCP connection with the sender. The mpls ldp discovery transport-address command provides a way to change the default behavior of the router. If the interface parameter is used, LDP advertises the IP address of the interface in the hello message on the interface. If the parameter is used, the LDP advertises the designated IP address in the hello message on the interface. If the configuration of the transmission address is changed during the precess of the running of the interface, ZXR10 router will delete the current adjacency relationship on the interface. If there is no other adjacent relationship maintaining the session maintained by the current adjacent relationship on the interface (multiple links do not exist), the session will be closed. The adjacency relationship (and the session) will be reestablished after a hello message is received from the peer.

Tip: If there are multiple links between routers, these routers must advertise the same transmission address on the corresponding interfaces.

Example

This example describes how to use the IP address of the interface as the transmission address on the interface oc3_2/1, and set the transmission address as 145.22.0.56 on the interface oc3_4/1. ZXR10(config#)interface oc3_2/1 ZXR10(config-if)#mpls ldp discovery transport-address interface ZXR10(config)#interface oc3_4/1 ZXR10(config-if)#mpls ldp discovery transport-address 145.22.0.56

mpls ldp egress Purpose


Use this command to control LDP to allocate popup labels to the designated indirectly connected destination networks (that is, the egress control policy). To disable this feature, use the no form of this command. Global configuration mpls ldp egress {for | nexthop } no mpls ldp egress {for | nexthop}

Syntax Description

for

Specifies which destination networks to which popup labels are allocated, range: 1~99

nexthop

Specifies the nexthop of the destination networks, range: 1~99

Defaults

By default, LDP allocates popup labels only to the directly connected networks and makes advertisements to the peer LSR.

Instructions

By default, LDP allocates popup labels only to the directly connected networks and makes advertisements to the peer LSR. For destination networks not directly connected, LDP acquires the idle label from the label pool as the incoming label and chooses the label value in the mapping message sent by the next hop of the route as the outgoing label. If local router is an edge LSR and the router of nexthop may be a non-MPLS router, local LSR cannot bind the outgoing label, and the received label packet be will discarded at the data layer because there is no outgoing label according to the MPLS framework protocol. In this case, it is necessary to configure the egress control policy to specify LDP to allocate popup labels to destination networks flowing out of MPLS network, and make advertises to the upstream LSR. Thus upstream LSR will forward the traffic from the MPLS network in the form of IP packets (or explicitly popup label packets). There are two kinds of control policies: based on destination network segment and based on next hop. 1. The egress control policy based on destination networks (mpls ldp egress for ) directly specifies which destination where local LSR is terminated. 2. The egress control policy based on next hop (mpls ldp egress nexthop ) specifies which neighbors are non-MPLS routers so that the traffic of these neighbors as next hops is the traffic out of MPLS. Local router allocates popup labels for this traffic. As long as a route meets either of the two policies, that is, the destination prefix is permitted by or the next hop is permitted by , the LDP will allocate a popup label to it. The policy takes effect only on the refreshed FECs after the configuration and does not reallocate labels to the existing FECs. There-


21


fore, it is not recommended to configure this command when the system is running to avoid inconsistency. Example

1. The router allocates popup labels to all subnet routes in networks 10.101.0.0/16 and 10.221.0.0/16, and allocates popup labels to all subnet routes in network 10.222.0.0/16 but not in 10.222.1.0/24. ZXR10(config)#ip access-list standard 10 ZXR10(config-std-nacl)#permit 10.101.0.0 0.0.255.255 ZXR10(config-std-nacl)#permit 10.221.0.0 0.0.255.255 ZXR10(config-std-nacl)#deny 10.222.1.0 0.0.0.255 ZXR10(config-std-nacl)#permit 10.222.0.0 0.0.255.255 ZXR10(config-std-nacl)#exit ZXR10(config)#mpls ldp egress for 10

2. The router allocates popup labels to all destination networks whose next hop are 100.1.1.3: ZXR10(config)#ip access-list standard 11 ZXR10(config-std-nacl)#permit 100.1.1.3 0.0.0.0 ZXR10(config-std-nacl)#exit ZXR10(config)#mpls ldp egress nexthop 11

mpls ldp explicit-null Purpose


Use this command to make the router which is supposed to advertise implicit null labels advertise explicit null labels. To disable this feature, use the no form of this command. Global configuration mpls ldp explicit-null [for ][to ] no mpls ldp explicit-null

22



Syntax Description


Example

for

Specifies the prefix of the explicit null labels replacing implicit ones, range: 1~99

to

Specifies which neighbors that the explicit null labels replaces implicit ones is advertised to, range: 1~99

By default, ZXR10 advertises directly connected networks to all neighbors by means of implicit null labels. �

By default, ZXR10 advertises directly connected networks to all neighbors by means of implicit null labels. The implicit null label causes the Penultimate Hop Poping (PHP) router to make PHP. Sometimes, however, it is prohibited for the PHP router to make such action so that the explicit null label is used in the outgoing label forwarding packet.

�

The mpls ldp explicit-null command enables the router to advertise explicit null labels to the neighbors permitted by and the directly connected networks permitted by . If the parameter is not specified in the command, explicit null labels will be advertised to all the directly connected networks; if the parameter is not specified in the command, explicit null labels will be advertised to all neighbors.

�

This command takes effect only to the label advertisement messages after the configuration. If labels have been advertised before the policy is configured, and the matched networks and neighbors will not change unless the session is interrupted and reestablished. Therefore, it is not recommended to configure this command when the system is running to avoid inconsistency.

1. This example describes how to make LDP advertise all direct routes by explicit null labels to all neighbors. ZXR10(config)#mpls ldp explicit-nul

2. This example describes how to advertise explicit null labels to the directly connected network 137.5.0.0, and advertise implicit null labels to other directly connected networks. ZXR10(config)#mpls ldp explicit-null for 10 ZXR10(config)#ip access-list standard 10 ZXR10(config-std-nacl)#permit 137.5.0.0 0.0.255.255 ZXR10(config-std-nacl)#deny any ZXR10(config-ext-nacl)#

mpls ldp graceful-restart Purpose Command Modes Syntax

Use this command to enable the router to support LDP Graceful restart function. Global configuration mpls ldp graceful-restart [timer {max-recovery | neighbor-liveness }]


23


no mpls ldp graceful-restart [timer {max-recovery | neighb or-liveness}] Syntax Description

Instructions

Example

max-recovery

Maximum time for LSR to wait for the label recovery of the peer neighbor (in seconds), it needs negotiation. range: 15~600, default: 120 seconds

neighbor-liveness

Maximum time for LSR to wait for the LDP session recovery (in seconds), it needs negotiation. range: 5~300, default: 120 seconds

�

This command is supported after the platform version 4.6.03.

�

By default, LDP does not support GR function. GR function is triggered by the corresponding configuration. But it needs LDP to reestablish neighbors or restart protocols to make this command take effect, because the relevant parameters negotiate in the initialized messages.

This example describes how to enable the router to support LDP GR function. The value of neighbor- liveness is configured as 30 seconds, and the value of max-recovery is configured as 40 seconds. ZXR10(config)#mpls ldp graceful-restart ZXR10(config)#mpls ldp graceful-restart timer neighbor-liveness 30 ZXR10(config)#mpls ldp graceful-restart timer max-recovery 40

mpls ldp neighbor password Purpose


Use this command to configure MD5 key for LDP to establish a TCP connection with a neighbor. To disable this feature, use the no form of this command. Global configuration mpls ldp neighbor password no mpls ldp neighbor password

Syntax Description


Address of the neighbor used in TCP connection or router ID identifying the neighbor, in the dotted decimal format

password

MD5 key used for establishing TCP connection with the neighbor, 3~80 characters

By default, there is no MD5 option in ZXR10 LDP session. MD5 authentication can be introduced between LDP peers to authenticate each TCP section. To enable MD5 authentication, both LSRs should be configured with authentication and use the same key; otherwise, the session cannot be established. If the key of the session with some neighbor is changed with the mpls ldp neighbor command (including the no form of this command), the current session is interrupted and a new session is established.

Example

This example describes how to establish a session with a neighbor whose TCP connection address is 140.2.1.15 by using abcdefg as the MD5 authentication key. ZXR10(config)#mpls ldp neighbor 140.2.1.15 password abcdefg

mpls ldp request-labels Purpose


Use this command to configure the prefix and downstream neighbors for which LDP sends request messages. To disable this feature, use the no form of this command. Global configuration mpls ldp request-labels for no mpls ldp request-labels

Syntax Description

Prefix access list for the request message to be sent, range: 1~99


25



Example

By default, ZXR10 does not send any request messages. �

This command enables the router to send label request messages for some prefixes. If the parameter is configured, the router will send label request messages to its downstream router with the prefix permitted by the list.

�

This command takes effect only on the FECs created after the configuration or those of the downstream LSRs discovered after the configuration. Therefore, it is not recommended to configure this command when the system is running to avoid inconsistency.

This example describes how to configure the router to send label request messages to the FEC in the network 10.1.1.0/16. ZXR10(config)#mpls ldp request-labels for 10 ZXR10(config)#ip access-list standard 10 ZXR10(config-ext-nacl)#permit 10.1.1.0 0.0.255.255 ZXR10(config-ext-nacl)#exit

mpls ldp router-id Purpose Command Modes Syntax

Use this command to configure the LDP router identifier. To disable this feature, use the no form of this command. Global configuration mpls ldp router-id [force] no mpls ldp router-id [force]

Syntax Description

Defaults

Specifies the IP address of an interface as the router identifier of LDP (if the interface is in the UP state)

force

Immediately changes the router identifier

By default, the election rules of LDP router identifier on ZXR10 are as follows: 1. Firstly, if the mpls ldp router-id command is used to designate the address of an interface as the router identifier, and the interface has an IP address and it is in the UP state, the address of the interface will be used as the router identifier. 2. Secondly, if there are loopback interfaces configured with IP addresses, the maximum IP address of the loopback interface will serve as the router identifier. 3. Lastly, among the IP addresses of interfaces configured with IP addresses and in the UP state, the maximum one is selected as the router identifier.

Instructions

26

By default, the automatically elected router identifier may be unavailable sometimes, for example, the routing protocol does not advertise the IP address elected as the router identifier to neighbors. In addition, the router configuration may cause the LPD router identifier is uncertain, and this invalidates the neighbor’s control policy.



The mpls ldp router-id command specifies the IP address of an interface as the router identifier. Note that the interface whose IP address serves as the router identifier must be in the UP state. If the optional parameter force is not specified, the router identifier specified by the mpls ldp router-id command will not take effect until the next router identifier election, and the router identifier takes place in the following cases: 1. LDP restarts. 2. The interface whose IP address serves as the current router ID is shut down. 3. The interface whose IP address is specified as the current router ID is not configured with any address. If the optional parameter force is specified, the effect of the m pls ldp router-id command depends on the current state of the specified interface. 1. If the specified interface is in the UP state and its address is not the current router identifier, the router will change the router identifier to the specified value, interrupt all the current sessions, release labels learned from the sessions, and terminate the MPLS forwarding related with the bounding of these labels. 2. If the specified interface is in the DOWN state, the router will change the router identifier to the specified value once the interface is in the UP state, interrupt all the current sessions, release labels learned from the sessions, and terminate the MPLS forwarding related with the bounding of these labels. Example

This example describes how to specify the IP address of the interface fei_1/1 as the router identifier. ZXR10(config)#mpls ldp router-id fei_1/1

VFI configuration and CFI MSPW configuration For VFI configuration mode, peer [spoke][tunnel ] no peer For VFI MSPW configuration mode, peer vcid no peer

Syntax Description

Defaults

IP address of the peer PE, in general it is the router identifier

spoke

If the optional parameter spoke is specified, the type of pseudo-wire is spoke; otherwise, it is hub

Tunnel number used for establishing VPLS, range: 1~1024

Different VPLS instances of the same PE has a different vcid, VPLS instances with the same vcid of the different PEs belongs to the same VPLS, range: 1~4294967294

The default peer type is “hub” in VFI configuration mode. The default peer type is “spoke” in VFI MSPW configuration mode.

Instructions

This command is supported after the platform version 4.6.02. This command is supported to be configured under vfi mspw configuration mode after the platform version 4.8.20. The current solution does not support the VPLS automatic discovery mechanism, thus it is necessary to specify all PE addresses in the same VPLS. This command uses the parameters specified in the vcid and pwtype commands to establish a pseudo-wire with the designated PE. The spoke type is used for VPLS hierarchy and cross-domain.

Example

1. This example describes how to execute the peer command in VFI configuration mode on the PE. ZXR10(config)#vfi vfi1


57


ZXR10(config-vfi)#peer 4.4.4.4

2. This example describes how to execute the peer command in VFI MSPW configuration mode on the PE. ZXR10(config)#vfi mspw vfi1 ZXR10(config-vfi-mspw)#peer 4.4.4.4 vcid 40

Related Commands

pwtype Purpose

Use this command to specify the type of a pseudo-wire established by the VPLS instance. Use this command to specify the type of a pseudo-wire in a static multi-hop pseudo-wire S-PE configuration instance.

Command Modes] Syntax Syntax Description

Instructions

VFI configuration or VFI MSPW configuration pwtype {ethernet | ethernet-vlan} ethernet | ethernet-vlan

Pseudo-wire type: Ethernet or Ethernet-vlan

This command is supported after the platform version 4.6.02. When a pseudo-wire is established between two PEs, there must be the negotiation about the type of the pseudo-wire established. There are two types of the pseudo-wire in VPLS: Ethernet and Ethernet-vlan. The establishment of a pseudo-wire will fail if the pseudo-wire types designated by PEs are different. The two pseudo-wire types correspond to two ways for providing the VPLS service. If the pseudo-wire type is Ethernet, the VPLS service is provided in the transparent mode. That is, the PE directly forwards the user data without checking or processing the vlan tag of the user data. In this case, the the vlan tag is regarded as the distinguisher for the user to manage private networks. In this mode, the input interface offered to the user must be the real interface. If the pw type is Ethernet-vlan, the VPLS service is provided in the rewrite mode. That is, the ingress PE router peels off the vlan tag in the user data and then forwards the pseudo-wire , while the egress PE attaches the corresponding vlan tag to the user data according to the outgoing interface type and then forwards it to the user.

Example

1. This example describes how to configure the pseudo-wire type in VFI configuration mode on the PE. ZXR10(config)#vfi vfi1 ZXR10(config-vfi)#pwtype Ethernet
