Hello everybody!

I would like to receive multicast stream on my VPS, located on my HN. Multicast is streamed from another server.

HN receives multicast perfectly, but VPS doesn't seems get multicast at all.

My configuration:
Kernel: kernel-2.6.18-ovz028stab053.5
Guest Os: opensuse-10-i386-default

I'm trying to receive multicast from VEID 103.
Vlan607 contains source of multicast stream.

I added veth103 interface to VE103 and assigned ip
#.#.96.83/29
gateway is #.#.96.81.

After that i assigned ip #.#.96.84/29 to br2 interface, as described in http://forum.openvz.org/index.php?t=msg&goto=26577& post

HN:

Dude, I don't think anyone runs multicast inside a VE. I've posted three or four times looking for help doing dynamic routing inside a VE with Quagga (and multicast routing) but gotten zero responses.

I don't see much point in using VETH if you can't get things like routing and streaming to work.

Don't get me wrong, OpenVZ is a great product. But not being able to dynamically announce a route to an IP within the VE is a serious road-block for me, and I can't understand why requests like this don't seem to generate any response. The only thing I can sumrise is that no one is doing it.

Guys, anybody? Pleeeeaaase .... ?? Pretty please ??? Wink
