[TriLUG] Multicast across VLANs - Cisco Specific

[Ryan Leathers]

I see. You may be able to do that using an ip multicast helper-map. 
Basically, this will map whatever multicast address you define to the IP 
address of a router that will "take it from there".  Google for "ip 
multicast helper" and see if that sounds like what you need.
