BIER FRR
========

Adoption: 8 for, 1 against
Greg: too much state
Tony P: we already have this state with IGP anyway
Hooman: is that just IGP protection nexthop?
Huaimo: we have FRR table for the nexthop
Thorless: sender/receivers do not change state so it's BIER
Hooman: but we'll have interop confusion about differnt FRR
Tony P: draft probably has to be very explicit about what happens when IGP
is signalling and in which cases you use this solution and what happens in
case of overlaps


INGRESS PROTECTION
==================

Huaimo: why detect failures nodes in the middle?
Greg/Sandy: it's the same as ingress protection. only mechanism we have is
