I'm trying to draw an example topology where a change causes a transient
multicast loop (with an "expected incoming adjacency" check) and I can't
find one. Unicast is sooo much easier ;-)
Have you observed temporary IP Multicast loops? (apart from the PIM SM
ones before ASSERTS where added). What was the topology and change
necessary to trigger those?
