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
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
end—Prompts user to take one of these actions:
