All things related to multicast

-----BEGIN PGP SIGNED MESSAGE-----

I just posted draft-nickless-ipv4-mcast-bcp-01.txt to the mboned mailing 
list, as well as to 

 for posting in the regular 
places.

- -01 is available immediately at

   http://www-fp.mcs.anl.gov/~nickless/draft-nickless-ipv4-mcast-bcp-01.txt

and in Microsoft Word format at

   http://www-fp.mcs.anl.gov/~nickless/draft-nickless-ipv4-mcast-bcp-01.txt

Updates include:

  - Explicitly mention that the internetwork must keep track of all
    sources under the ASM model.

  - Changed the wording of the BGP NLRI=Multicast semantic description
    from "<foo> means <bar>" to "<foo> is currently interpreted to mean
    <bar>".  My intent here is to describe what's going on in the
    real world of implementation and deployment, while avoiding the
    minefield of overloading existing definitions (or lack thereof).

  - Changed the inter-AS peering description to describe the use of
    any join/forward protocol that supports (S,G) joins.  PIM-SM
    used as the specific example currently used.

  - Explained the interpreted semantics of NLRI=Multicast in the
    historical context of controlling DVMRP forwarding topology.

  - Added the SAFI=3 case (both unicast and multicast).

  - Defined the term "PIM Sparse Mode domain".

  - Mentioned that there is generally one PIM Sparse Mode Domain
    per Autonomous System.

  - Explicitly stated that under SSM there is no need for PIM Sparse
    Mode Rendezvous Points.

  - Expanded on the use of IGMP over PPP connections (dialups).

  - Added reference to Core Based Trees in the MSDP section.

  - Expanded explanation of peering TTL 32 barrier.

  - Added description of PIM Sparse Mode Denial of Service vulnerabilities.

  - Expanded acknowledgements.

Please continue to comment and suggest updates.  Again I thank everyone who 
has read the -00 draft, and especially thank those who have sent feedback.
