Configuring RSVP-TE Graceful Restart

Configure RSVP-TE graceful restart to enable routers to maintain MPLS forwarding
state when a link or node failure occurs. Becasue forwarding state is maintained,
traffic can continue to be forwarded while RSVP-TE restarts and recovers. The RSVP-TE
graceful restart feature enables an LSR to gracefully restart, to act as a graceful restart
helper node for a neighboring router that is restarting, or both.
To configure RSVP-TE graceful restart on the current VR so that the LSR acts as both
a graceful restart restarting node and a graceful restart helper node:

To configure RSVP-TE graceful restart on the current VR so that the LSR acts as only
a graceful restart helper node for neighbors that support RSVP-TE graceful restart:

Enable RSVP-TE graceful restart on the current virtual router.
host1(config)#mpls rsvp signalling hello graceful-restart
(Optional) Configure the recovery time the time within which you want
neighboring routers to resynchronize RSVP-TE state and MPLS forwarding state
after a graceful restart.
host1(configf)#mpls rsvp signalling hello graceful-restart recovery-time 140000
(Optional) Configure the restart time the time within which the sender gracefully
restarts RSVP-TE and reestablishes hello communication with RSVP-TE neighbors.
