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.

# Gracefully restart MPLS LDP.

<Sysname> graceful-restart mpls ldp 

graceful-restart timer neighbor-liveness timer

MPLS LDP view

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

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.

# Set the LDP neighbor liveness time to 100 seconds.
