All,

I’ve been selected as an MPLS-RT reviewer for draft-zzhang-mpls-rmr-multicast,
which is currently a candidate for MPLS WG adoption.

In the abstract is stated:
   With Resilient MPLS Rings (RMR), although all existing multicast
   procedures and solutions can work as is, there are optimizations that
   could be done for RSVP-TE P2MP tunnel signaling and Fast-ReRouting
   for both mLDP and RSVP-TE P2MP tunnels.
I have carefully read the draft but I could not find any justification
for the optimisation that could be done.
I also did not find any indication how this optimisation has to be
deployed. Do all the nodes in the ring, or in the network have to
support this optimisation before it becomes effective.

I think these issues have to be documented before this draft can
be adopted as WG draft.

Best regards, Huub.
