Version Description

9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information When you enable soft-reconguration for a neighbor and you execute the clear ip bgp soft in command,
the update database stored in the router replays 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 negotiated
(after execution of clear ip bgp soft in), BGP sends a route-refresh request to the neighbor and receives
all of the peer’s updates.
