Configure keepalive timeout interval for targeted LDP sessions using the

Quick Steps for Configuring LDP Graceful Restart
The graceful restart mechanism is always enabled for the switch. The following steps provide a quick tuto-
rial for configuring the graceful restart helper status and timers:
1
Enable the Graceful Restart Helper for the switch using the
helper command. For example:
-> configure router ldp graceful-restart-helper
2
Configure the reconnect time advertised to neighboring LDP routers using the
reconnect-time command. For example:
-> configure router ldp reconnect-time 300
3
Configure the MPLS forwarding state hold time using the
time command. For example:
-> configure router ldp fwd-state-holding-time 300
4
Configure the amount of time stale label-FEC bindings are retained using the
maximum-recovery-time
-> configure router ldp maximum-recovery-time 300
5
Configure the amount of time to wait for a neighbor to re-establish an LDP session using the
router ldp neighbor-liveness-time
-> configure router ldp neighbor-liveness-time 300
Note. Optional. Verify LDP parameter settings using the
example:
