I don't see any page in wiki about multicast setup, so I will (slowly) write one. This will be my first try with multicast on a SixXS tunnel, so a few hints would be welcome: - if I have a single PC as tunnel endpoint, with no subnet, is ecmh required to run? - can regular hosts with Teredo tunnels (Vista, miredo, etc) receive multicast traffic from my PC? - if not, how can I do tests (one host sending, other receiving)? Request another SixXS tunnel? Or an IPv6 tunnel from other provider (like go6, etc..)? Would that work? Can I get access to m6bone some other way? More to come... David

I'd love to play a little with IPv6 multicast. Back in the good University days I got the original Mbone connection setup and did quite a few demos using vic/vat/nv on the NASA TV feed from the USA. There was no video on the Internet back then, we're talking 1993/1994... ;-) What strikes me as odd is this bit of the SixXS multicast FAQ: I am wondering, why is the underlined part needed at all? These routers belong to the many ISPs that my AYIYA tunnel traverses on the way to the SixXS PoP, I don't see why I should bother do anything with the IPv4 routers that handle my AYIYA tunnel... Now, I should get my tunnel fixed before I can do a multicast test, but that's a different story... :-) Ciao, Luca

That "status" is experimental for the SixXS PoPs. For IPv6 Multicast is a more or less a requirement, otherwise things like Neighbor Discovery and Router Advertisements would not even work. Routing IPv6 Multicast is a completely different story though, and for mostly the same reasons as IPv4, it is hard to get a good setup and have it working correctly without taking a completely network down. As such, we have marked IPv6 Multicast on the SixXS PoPs as experimental, one can thus play with it, but we can't guarantee that it will work though.
