Command Modes
ROUTER BGP
Usage
Information
When soft-reconfiguration is enabled for a neighbor and the clear ip bgp soft in is executed,
the update database stored in the router is replayed and updates are reevaluated. With this
command, the replay and update process is triggered only if route-refresh request is not
negotiated with the peer. If the request is indeed negotiated (upon execution of
clear ip bgp
soft in
), then BGP sends a route-refresh request to the neighbor and receives all of the peer’s
updates.
