"bgp fast-external-fallover" issue

[alex goshtaei]

Hi All, 

we are using multiple routers running BGP with static route with 200 AD as a backup connection. we're using "bgp fast-external-fallover" command to not wait for hold timer in failover scenario and switch to static route immediately. all routers with 15.x version switch to static route immediately, except one router 3845 with 12.4(24)T5 version. it takes 3 min to switch to static route. also after apply this command "bgp fast-external-fallover", still I can't see this command in "show run all | sec bgp". is there any bug with with release ? any suggestion would be very appreciated. 

thanks 

Alex

Hello,

bgp fast external failover is enabled by default, you won't see it in your running config. I am not sure about your IOS version, but you can try and enable it on an interface as well:

Router(config-if)#ip bgp fast-external-failover ?

There should be an option to permit it.
