This section provides a configuration example for the MPLS TE—RSVP Graceful Restart feature.

In the following example, graceful restart is enabled, and related parameters, including a DSCP value, a 
refresh interval, and a missed refresh limit are set.

Router# configure terminal

Enter configuration commands, one per line.  End with CNTL/Z.

Router(config)# ip rsvp signalling hello graceful-restart mode help-neighbor

Router(config)# ip rsvp signalling hello graceful-restart dscp 30

Router(config)# ip rsvp signalling hello graceful-restart refresh interval 10000

Router(config)# ip rsvp signalling hello graceful-restart refresh misses 4

Router(config)# end

The following example verifies the status of graceful restart and the configured parameters:

Router# show ip rsvp hello graceful-restart
