host1:vr5(config)#mpls rsvp signalling hello

2. (Optional) Configure the refresh interval.

host1(config-if)#mpls rsvp signalling hello refresh interval 5000

3. (Optional) Configure the refresh misses.

host1(config-if)#mpls rsvp signalling hello refresh misses 5

To configure the RSVP-TE hello feature on a RSVP-TE specific interface:

1. Access the interface.

host1(config)#interface fastEthernet 4/3

2. Issue the mpls rsvp signalling hello command.

host1(config-if)#mpls rsvp signalling hello

3. (Optional) Configure the refresh interval.

host1(config-if)#mpls rsvp signalling hello refresh interval 5000

4. (Optional) Configure the refresh misses.

host1(config-if)#mpls rsvp signalling hello refresh misses 5

NOTE: Issuing the refresh interval or the refresh misses keywords only configures the

refresh values; this action has no effect on enabling or disabling hellos.

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:

1. Enable RSVP-TE graceful restart on the current virtual router.

host1(config)#mpls rsvp signalling hello graceful-restart

2. (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
