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.

Dell>show ip bgp peer-group

Configuring BGP Fast Fail-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 fail-

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.
