■
Use to enable the BGP graceful restart capability.
■
Advertisement of the graceful restart capability is enabled 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, 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.
■
Specify an interval longer than the restart time.
