Route Refresh

If the router detects that a peer supports both Cisco-proprietary and standard route
refresh messages, it will prefer to use the standard route refresh messages.

Selecting the Best Path
Example
host1(config-router)#neighbor graceful-restart restart-time 240
Use the no version to restore the default value, 120 seconds.
See neighbor graceful-restart restart-time.
Use to set the maximum time BGP waits to receive an End-of-RIB marker from
the specified restarted peer or peer group 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.
This command takes effect immediately and automatically bounces the session.
Example
host1(config-router)#neighbor graceful-restart stalepaths-time 480
Use the no version to restore the default value, 360 seconds.
See neighbor graceful-restart stalepaths-time.
Use to control the advertisement of BGP capabilities to peers. Capability
negotiation and advertisement of all capabilities are enabled by default.
You can specify the deprecated-dynamic-capability-negotiation,
dynamic-capability-negotiation, four-octet-as-numbers, orf, route-refresh,
and route-refresh-cisco capabilities. The graceful restart capability is controlled
by specific graceful-restart commands.
If you specify a BGP peer group by using the peerGroupName argument, all the
members of the peer group inherit the characteristic configured with this
command unless it is overridden for a specific peer.
You cannot configure the receive direction for the orf capability for a peer that
is a member of a peer group or for a peer.
If you issue the route-refresh or route-refresh-cisco keywords, the command
takes effect immediately. If dynamic capability negotiation was negotiated for
the session, a capability message is sent to inform the peer of the new capability
configuration. If dynamic capability negotiation was not negotiated for the session,
the session is bounced automatically.
