mpls ldp graceful-restart

Use this command to enable the router to support LDP Graceful
restart function.
Global configuration
mpls ldp graceful-restart [timer {max-recovery <interval>|
neighbor-liveness <interval>}]
no mpls ldp graceful-restart [timer {max-recovery | neighb
or-liveness}]
max-recovery
<interval>
neighbor-liveness
<interval>
� 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 com-
mand 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 sec-
onds.
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
