Configuring BGP soft-reset
After you modify the route selection policy, for example, modify the preferred value, you must reset
BGP sessions to apply the new policy. The reset operation tears down and re-establishes BGP
sessions.
To avoid tearing down BGP sessions, you can use one of the following soft-reset methods to apply
the new policy:
•
Enabling route-refresh—The BGP router advertises a route-refresh message to the specified
peer, and the peer resends its routing information to the router. After receiving the routing
information, the router filters the routing information by using the new policy.
This method requires that both the local router and the peer support route refresh.
•
Saving updates—Use the peer keep-all-routes command to save all route updates from the
specified peer. After modifying the route selection policy, filter routing information by using the
new policy.
This method does not require that the local router and the peer support route refresh but it uses
more memory resources to save routes.
