Hi!  Thanks for your review!

That is meant to be the Packed Capability, hence "P".  But you bring
up a good point in that the terminology is not consistent.  The text
should be consistent in using "packet capability" (vs just
"capability").

OK

Each PIM message has a separate field of flag bits.  rfc5059 uses bit
7 in the Bootstrap message (only).  Bit 7 in the Register-Stop message
is not used.


I had originally thought that  Section 2 was referring to one of the new messages this draft introduced but actually it was extending an existing PIM-SM message, Register-Stop. So this draft introduces two new PIM-SM messages and also modifies one message to indicate packing capability.

Thanks!
