Configuring BGP4+ graceful restart stale routes timer
Use the following command to specify the maximum amount of time a helper device will wait for an end-
of-RIB message from a peer before deleting routes from that peer.
device(config-bgp)# graceful-restart stale-routes-time 120
Syntax: [no] graceful-restart stale-routes-time seconds
The seconds variable sets the maximum time before a helper device cleans up stale routes. The
allowable range is 1 to 3600 seconds. The default value is 360 seconds.
Configuring BGP4+ graceful restart purge timer
Use the following command to specify the maximum amount of time a device will maintain stale routes
in its routing table before purging them.
device(config-bgp)# graceful-restart purge-time 900
Syntax: [no] graceful-restart purge-time seconds
The seconds variable sets the maximum time before a restarting device cleans up stale routes. The
allowable range is 1 to 3600 seconds. The default value is 600 seconds.
Displaying BGP4+ graceful restart neighbor information
To display BGP4+ graceful restart information for BGP4 and BGP4+ neighbors, enter the show ipv6
bgp neighbors command.
device# show ipv6 bgp neighbors
