All things related to multicast

[Richard Mavrogeanes <>]

Ken,

Extreme Networks has excellent IGMPV2 performance, including
snooping.  We moved there having left the CGMP "does not scale"
world.  Foundry is equally good, Nortel not so good (Long timeouts).
Cisco is okay, but they want you to use their proprietary methods.

Hope this helps.
