The configuration of the peer group is maintained, but it is notapplied to the peer group members. When you disable a peer group, all the peers within the peer groupthat 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 Privilegemode, as shown in the following example.Dell>show ip bgp peer-groupPeer-group zanzibar, remote AS 65535BGP version 4Minimum time between advertisement runs is 5 secondsFor address family: IPv4 UnicastBGP neighbor is zanzibar, peer-group internal,Number of peers in this group 26Peer-group members (* - outbound optimized):10.68.160.110.68.161.110.68.162.110.68.163.110.68.164.110.68.165.110.68.166.110.68.167.110.68.168.110.68.169.110.68.170.110.68.171.110.68.172.110.68.173.110.68.174.110.68.175.110.68.176.110.68.177.110.68.178.110.68.179.110.68.180.110.68.181.110.68.182.110.68.183.110.68.184.110.68.185.1Dell>Configuring BGP Fast Fall-OverBy 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 fastfall-over feature reduces the convergence time while maintaining stability. The connection to a BGP peeris immediately reset if a link to a directly connected external peer fails.Border Gateway Protocol IPv4 (BGPv4) 183
