Yes, this is how we run all of our router interfaces right now. We would 
like to do v3 for SSM and keep some sort of snooping capability to limit 
flow to the listening ports in a L2 device.

We could wait on all of this (running IGMPv3 and being able to snoop it) 
but we found out that HP was going to discontinue (End-of-life, 
End-of-sales, End-of-development) their 4000 line by the end of the year. 
Talking to HP engineers they said that since IGMPv3 is not an RFC yet 
they're policy is not to work on it.

In our case this is a big deal since we have several hundreds of their 
4000s and we would like to move on to v3 where we want to use it. I guess 
what we were trying to do was to find out how many schools out there would 
be affect it by HP's move. 

I was also curious about the status of IGMPv3 in the process and what is 
missing to make it into an RFC.

Thx,

José.
