Make sure you have the very latest firmware for the Extreme.  

We've run into a very similar issue with a Summit 48 (no i), and the 
essence seems to be "Extreme switches know that multicast is specialy in
some way, but they don't *really* know what to do with it, so the boxes 
just drop every other multicast packet".

Effectively killing OSPF and EIGRP...
