more memory resources to save routes.
•
Manual soft-reset—Use the refresh bgp command to enable BGP to send local routing
information or advertise a route-refresh message to the specified peer. The peer then resends
its routing information. After receiving the routing information, the router filters the routing
information by using the new policy.
