This then devolves into a discussion about how tight you want your timers to run; in my case, reasonably but not very. If you have bouncy links with tight timers, you can run into edge cases which will cause pretty serious network disruption due to constant reconvergence of igp/ibgp. ## Also, bfd isn't supported universally yet, or even supported very well in the places that it does work.
