Usage Guidelines The amount of time a router waits for an LDP session to be reestablished is the lesser of the following
va
lues:
• The value of the peer’s fault tolerant (FT) type length value (TLV) reconnect timeout
• The value of the neighbor liveness timer
If the router cannot reestablish an LDP session with the neighbor in the time allotted, the router deletes
t
he stale label-FEC bindings received from that neighbor.
Examples The command in the following example sets the amount of time that the router should wait for an LDP
se
ssion to be reestablished to 30 seconds:
Router(config)# mpls ldp graceful-restart timers neighbor-liveness 30
secs The amount of time (in seconds) that the router should wait for an LDP
session to be reestablished. The default is 120 seconds. The range is 5 to
300 seconds.
