Hi Greg,

Just to be clear, this is purely a suggestion on my part that might improve
the document.  It's not a DISCUSS, so you're not obligated to indulge my
suggestions unless you think they're a worthwhile improvement.

Yes, those all look good to me.  For the 4.2 changes, I might suggest a
slightly different presentation:

NEW:

When a PE supporting this specification receives a C-multicast route for a
particular (C-S, C-G) for which all of the following are true:

o the RT carried in the route results in importing the route into a
particular VRF on the PE;

o the route carries the Standby PE BGP Community; and

o the PE determines (via a method of failure detection that is outside the
scope of this document) that C-S is not reachable through some other PE
(more details are in Section 4.3),

then the PE MAY install VRF PIM state corresponding to this Standby BGP
C-multicast route (the result will be that a PIM Join message will be sent
to the CE towards C-S, and that the PE will receive (C-S, C-G) traffic),
and the PE MAY forward (C-S, C-G) traffic received by the PE to other PEs
through a P-tunnel rooted at the PE.
