fast-external-fallover

Resets the session if a link to an eBGP peer goes down.
Syntax
fast-external-fallover
no fast-external-fallover
Modes

BGP configuration mode

Usage Guidelines

Use this command to terminate and reset external BGP sessions of a directly adjacent peer if the link to the peer goes down, without waiting for the timer, set by the BGP timers command, to expire. This can improve BGP conversion time, but can also lead to instability in the BGP routing table as a result of a flapping interface.

Examples

The following example configures the device to reset the session if a link to an eBGP peer goes down. 

device# configure terminal
device(config)# router bgp
device(config-bgp-router)# fast-external-fallover
