From 88fc83eb716bf07f4634de6de5b569f795a56418 Mon Sep 17 00:00:00 2001 From: Neale Ranns Date: Wed, 5 Apr 2017 08:11:14 -0700 Subject: BFD-FIB interactions - single-hop BFD: attach a delegate to the appropriate adjacency - multi-hop BFD [not supported yet]: attach a delegate to the FIB entry. adjacency/fib_entry state tracks the BFD session state. when the state is down the object does not contribute forwarding hence and hence dependent objects will not use it. For example, if a route is ECMP via two adjacencies and one of them is BFD down, then only the other is used to forward (i.e. we don't drop half the traffic).
