1540 CHAPTER 95: MPLS BASICS CONFIGURATION COMMANDS

Description Use the graceful-restart mpls ldp command to gracefully restart MPLS LDP.

Note that:

■This command is used to test MPLS LDP GR without main/backup failover. It is not recommended in normal cases.

■The MPLS LDP GR capability is required for this command to take effect.

Related commands: graceful-restart (MPLS LDP view).

Example # Gracefully restart MPLS LDP.

<Sysname> graceful-restart mpls ldp

graceful-restart timer neighbor-liveness

Syntax graceful-restart timer neighbor-liveness timer

undo graceful-restart timer neighbor-liveness

View MPLS LDP view

Parameter timer: LDP neighbor liveness time, in the range 60 to 300 seconds.

Description Use the graceful-restart timer neighbor-liveness command to set the LDP neighbor liveness time.

Use the undo graceful-restart timer neighbor-liveness command to restore the default.

By default, the LDP neighbor liveness time is 120 seconds.

Note that:

■Modifying the LDP neighbor liveness time removes the existing sessions and the LSPs based on the sessions, which need to be reestablished.

■For LDP sessions with MD5 authentication configured, you need to increase the LDP neighbor liveness time appropriately so that the TCP connection can be reestablished.

Example # Set the LDP neighbor liveness time to 100 seconds.
