I have two OC3 connections to my ISP, one primary and one backup. I am also running BGP. Both routers are 7204VXRs running 12.4(11)T series and are located in physically seperate buildings for survivability reasons. They are connected via fiber and are on seperate networks.
Currently, I have a VERY VERY long wait for BGP to settle down after a loss of the primary OC3.
To combat this, I was looking into using BFD. The only problem is BFD can only be configured on an Ethernet-type port. This means I cannot configure it on my POS port.
How would I setup BFD to make this work? My plan is to configure BFD on the gig0/1 ports of both routers and setup the neighbor fall-over bfd command to point to the BGP neighbor of each respective router.
Would this work?
You are very welcomed, BFD is currently only supported on Ethernet, FastEthernet, and GigabitEthernet interfaces, thus the router on which you want to use BFD with BGP, the interface connected to its neighbor must be an Ethernet interface, i don't know how you are setting all your routers, but this is how it should go.
I hope that i've been informative.
