To disable a peer group, use the neighbor peer-group-name shutdown command in 
CONFIGURATION ROUTER BGP mode. The configuration of the peer group is maintained, but it is not 
applied to the peer group members. When you disable a peer group, all the peers within the peer group 
that are in the ESTABLISHED state move to the IDLE state.

To view the status of peer groups, use the show ip bgp peer-group command in EXEC Privilege 
mode, as shown in the following example.

Configuring BGP Fast Fall-Over

By default, a BGP session is governed by the hold time.
BGP routers typically carry large routing tables, so frequent session resets are not desirable. The BGP fast 
fall-over feature reduces the convergence time while maintaining stability. The connection to a BGP peer 
is immediately reset if a link to a directly connected external peer fails.
