Enabling Graceful Restart

Enabling Graceful Restart
Perform this task to enable graceful restart for implementations using both node-id and interface-based hellos.
RSVP graceful restart provides a control plane mechanism to ensure high availability, which allows detection
and recovery from failure conditions while preserving nonstop forwarding services.
SUMMARY STEPS
1. configure
2. rsvp
3. signalling graceful-restart
4. signalling graceful-restart interface-based
5. Use the commit or end command.
DETAILED STEPS
Command or Action
Step 1 configure
Example:
RP/0/RSP0/CPU0:router# configure
Step 2 rsvp
Example:
RP/0/RSP0/CPU0:router(config)# rsvp
Step 3 signalling graceful-restart
Example:
RP/0/RSP0/CPU0:router(config-rsvp)#
signalling graceful-restart
Step 4
signalling graceful-restart interface-based
Example:
RP/0/RSP0/CPU0:router(config-rsvp)#
signalling graceful-restart interface-based
Step 5 Use the commit or end command.
