Hi

The good version looks pretty good. But I noticed one more thing that
you might want to change. I'll leave it to you.

8.1.1.  The MLD Querier is Co-Located with the mAFTR

   The mAFTR can embed the MLD Querier function (as well as the PIMv6
   DR) for optimization purposes.

I'm wondering if you should say IPv6 DR or PIMv6 DR instead. As you
write after the heading, it must be co-located with the DR as well.
Normally the querier would be the same router, but the querier could
be another router on the link.

Then we have this section:

8.1.2. The DR is Co-Located with the mAFTR

In the text you talk about the DR connected to the IPv4 source. Hence
it is the first hop DR, and IPv4 DR. I'm wondering if it is worth
saying IPv4 DR or something in the title to distinguish it from the
other DR. Basically we have first hop DR and last hop DR, or if you
like IPv4 DR and IPv6 DR.

I'm leaving it to you to decide. This is the only remaining issue I
can find. There is a typo at the end of Appendix B though. It say
"Noet".

Stig
