Hi Thomas,
For many operators its not "the vendor" but multiple vendors, and that'swhy many operators (and apparently other IETF contributors too) see an interest in standardizing one solution, with options where needed, and not multiple profiles.
In your last email you say "..Misunderstanding: the draft says "MUST" for both PIM-based and BGP-based C-multicast routing."
How is that going to help you standardizing one solution? I also pointed out earlier that the Morin draft does not say which core tree building protocol needs to be used. This also does not help in getting an interoperable solution.
Thx, Ice.
