Figure 8-21. Command example: show ip bgp peer-group
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.
