■ Use to enable the BGP graceful restart capability.
■ Advertisement of the graceful restart capability is disabled by default.
■ The no neighbor capability negotiation command prevents the advertisement
of all BGP capabilities, including graceful restart, to the specified peers.
■ This command takes effect immediately and automatically bounces the session.
■ Example
host1(config-router)#bgp graceful-restart
■ Use the no version to disable advertisement of the graceful restart capability.
Use the default version to restore the default condition, of not advertising this
capability.
■ See bgp graceful-restart.
bgp graceful-restart path-selection-defer-time-limit
■ Use to set the maximum time a restarted BGP speaker defers reinitiating the
best-path selection process.
■ This command takes effect immediately and automatically bounces the session.
■ Example
host1(config-router)#bgp graceful-restart path-selection-defer-time-limit 180
■ Use the no version to restore the default value, 120 seconds.
■ See bgp graceful-restart path-selection-defer-time-limit.
bgp graceful-restart restart-time
■ Use to set the time BGP advertises to all peers within which it expects to
reestablish a session after restarting. Peers flush stale routes from the speaker
if the session is not restarted within this period.
■ Specify an interval shorter than the stalepaths time.
■ This command takes effect immediately and automatically bounces the session.
■ Example
host1(config-router)#bgp graceful-restart restart-time 240
■ Use the no version to restore the default value, 120 seconds.
■ See bgp graceful-restart restart-time.
bgp graceful-restart stalepaths-time
■ Use to set the maximum time BGP waits to receive an End-of-RIB marker from
any restarted peer before flushing all remaining stale routes from that peer. The
timer begins when BGP recognizes that the peer session has gone down.
■ This command prevents an excessive delay in BGP reconvergence due to a peer
that brings a session back up but is slow to send fresh routes.
