That is, within each link, routers should not rely on link multicast to exchange multicast control messages and should have TCP mesh between them over which the messages can be exchanged reliably even if there is congestion, which is what I did in 2001 with SRSVP (Simple RSVP, a stable and hierarchical unicast/multicast QoS routing protocol without crank back).
