remarks- source specific multicast for IP

[Ali Boudani <aboudani@irisa.fr>]

Hello,
just a few remarks
1- Elimination of cross-delivery of traffic when two sources
    simultaneously use the same source-specific destination address.
    The simultaneous use of an SSM destination address by multiple
    sources is explicitly supported.

You are supposing that the delivery is done usually by shared tree??
but in all cases the use of ssm will not eliminate the cross-delivery
because it is not a protocol matter more than topology matter??
isnt true?

2- the adding of SSM upgrades to the existing protocol hasnt any impact
in scalability in building multicast trees??

3- is the source address should be in teh range 232/8 also or it is just
for the group ??


Thanx
