[pim] Re: pim WGLC for draft-ietf-pim-gaap-06

Hi working group and authors.

Sorry for a slow response to this. I wanted to take some time to
review the document myself.

Based on the responses the draft passed wglc. But I think some changes
are needed.

Here is my review.

In 2. Definition of Terms:

      GAAP Group Address:  is an IANA assigned non-link-local group address
      the GAAP protocol sends messages to.  This address must not come
      from the GAAP multicast address block allocated by IANA.

Do we need to mention IANA and that it is not from the other block?
This is explained in the IANA considerations. Isn't it sufficient here
to just list the exact addresses. Maybe put TBD1 and TBD2 as
placeholders?

In 4. GAAP Message Format:

It is not clear to me what exactly the Timestamp is. Is 32 bits
enough? Should it be 64 bits?

Are records aligned or will the next record come immediately after the
Group Name of the previous record?

In 7. Security Considerations:

I believe all applications need to support the same encryption
mechanism and have the same keys. This could be difficult in some
cases. For instance I think it would be great if embedded devices that
today use a fixed IANA assigned address could make use of GAAP
instead.

In 8.3.:

A /8 block is requested from IANA, but this does not fit within the
current blocks IANA is assigning from. We will need some discussion
within IETF and with IANA on how to deal with this. This is a really
big portion of the IPv4 multicast space. Does it need to be this
large?

The IPv6 range here is 28 bits, while 6.1 seems to assume 32 bits.

Regards,
Stig
