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.
<Sysname> system-view
[Sysname] mpls ldp
[Sysname-mpls-ldp] graceful-restart timer neighbor-liveness 100
