Configuring graceful restart

OSPFv3 routing can be gracefully restarted on switches without losing packets that are in transit. There is no effect on the saved switch configuration.


Graceful restart is only applicable to the 6300-VSF and 6400, not for 832x switches.

You must be in the OSPFv3 router configuration context, as indicated by the switch(config-ospfv3-1)# prompt.

Configure graceful restart of using the following command. For command details, see graceful-restart.

graceful-restart [restart-interval <seconds> | helper]

For example, the following command specifies 50 seconds as the maximum interval another router will wait for this router to gracefully restart.
switch(config-ospfv3-1)# graceful-restart restart-interval 50
