Cisco CRS Configuration Guide

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.

DETAILED STEPS
PurposeCommand or Action
Enters global configuration mode.configure
Example:
RP/0/RP0/CPU0:router# configure
Step 1
Enters the RSVP configuration mode.rsvp
Example:
RP/0/RP0/CPU0:router(config)# rsvp
Step 2
Enables the graceful restart process on the node.signalling graceful-restart
Example:
RP/0/RP0/CPU0:router(config-rsvp)#
Step 3
signalling graceful-restart
Enables interface-based graceful restart process on the node.signalling graceful-restart interface-based
Example:
RP/0/RP0/CPU0:router(config-rsvp)#
Step 4
signalling graceful-restart interface-based
commit—Saves the configuration changes and remains within
the configuration session.
Use the commit or end command.
Step 5
