As per: http://www.sixxs.net/faq/connectivity/?faq=comparison

Yes, GRE can do it, but as listed there many others do too.

The trick is that at either end of the tunnel you will have to run a MLD
proxy or a real multicast router for things to work.
(ecmh amongst many others can achieve this)

You state you have a 'hybrid network', why is that network not native?

Greets,
