BGP peer sessions

[menace212]

I have a BGP session with a number peers on a vlan. The subnet is a /25 and I would like to change it to a /24. Will this subnet change restart the BGP session with the peers?

its a tcp session, as long as the IP stays the same, and connection is not interrupted, it shouldn't effect it.

in order to get bgp to route the new subnet you will need to clear the session - it is possible that just adding it to the interfaces that it will not change in the routing table because nothing has forced it to change. clear ip bgp * - this will clear all bgp sessions and force the routing table to be updated
