Re: [MBONED] draft-ietf-mboned-64-multicast-address-format-03.txt

Hi Behcet, all,

I was planning to send an e-mail to the list to notify the main changes we implemented in -03. Since you started this thread, I will use it for that purpose. 

The main changes are as follows:

* Abandon the M-bit idea

* Reserve two prefixes to be used for the algorithmic translation of an IPv6 multicast address into an IPv4 one; and vice versa
(1) ff3x:0:8000::/96 for SSM
(2) ffxx:8000::/20 for ASM

* Explain the rationale for selecting a /96 (SSM) and /20 (ASM)

* The document does not update RFC4291; i.e., no change to the IPv6 addressing architecture.

Cheers,
Med
