BGP neighbor fall-over feature

Can anyone tell me how the BGP neighbor fall-over feature works? I'm wondering how it's different from fast-external-fallover.

I've read the description here:

but I still can't tell exactly what it's doing.

Best Regards,

Re: BGP neighbor fall-over feature

If I may, I'll add a little more detail to my question.

What I'm after is a way to improve convergence in the event of an indirect failure between two eBGP peers. For example, if I'm doing physical peering, but I've got a layer 2 filtering device in the path, there's a possibility that the interface will stay up, but the connectivity will be broken. In this case, the fast-external-fallover feature won't help me and I'll have to rely on timers to bring the BGP session down. I was hoping that this neighbor fall-over feature would help me out in some way, but I'm not sure how it works.

Best Regards,

Rich
