NOTE: If you configure graceful restart after a BGP or LDP session has been
established, the BGP or LDP session restarts and the peers negotiate graceful
restart capabilities. Also, the BGP peer routing statistics are reset to zero.
Configuring Graceful Restart Options for BGP
To configure the duration of the BGP graceful restart period, include the
restart-time
statement at the [edit protocols bgp graceful-restart] hierarchy level. To set the length
of time the router waits to receive messages from restarting neighbors before declaring
them down, include the
stale-routes-time
statement at the
[edit protocols bgp
graceful-restart] hierarchy level.
[edit]
protocols {
bgp {
graceful-restart {
disable;
restart-time seconds;
stale-routes-time seconds;
}
}
}
routing-options {
graceful-restart ;
}
To disable BGP graceful restart capability for all BGP sessions, include the disable
statement at the [edit protocols bgp graceful-restart] hierarchy level.
NOTE: To set BGP graceful restart properties or disable them for a group,
include the desired statements at the
[edit protocols bgp group group-name
graceful-restart]
hierarchy level.
To set BGP graceful restart properties or disable them for a specific neighbor
in a group, include the desired statements at the
[edit protocols bgp group
group-name neighbor ip-address graceful-restart] hierarchy level.
NOTE: Configuring graceful restart for BGP resets the BGP peer routing
statistics to zero. Also, existing BGP sessions restart, and the peers negotiate
graceful restart capabilities.
