fast-external-failover (BGP)

Resets the session if a link to an EBGP peer goes down.

Synopsis fast-external-failover

no fast-external-failover

Operands None

Defaults This option is disabled.

Command Modes BGP configuration mode

Description Use this command to terminate and reset external BGP sessions of an directly adjacent peer if the

link to the peer goes down, without waiting for the timer, set by the BGP timers command, to

expire.

Usage Guidelines This can improve BGP conversion time, but can also lead to instability in the BGP routing table as a

result of a flapping interface.

Use the no form of this command to restore the default.

Examples To configure the device to reset the session if a link to an EBGP peer goes down:

switch(config)# rbridge-id 10

switch(config-rbridge-id-10)# router bgp

switch(config-bgp-router)# fast-external-failover
