Hi Guys,

I have written some code to do IGMPv3 SSM subscriptions, but need to test it, I got hold of a 2821 which I
have free range to do whatever to, I am also free to assign client and source addresses at will.

I have beaten my head against this thing for a few days, I can do stuff like pinging between machines, I even got it to understand stuff is flowing in and I have made a subscription, it even tells me (show mroute) that traffic from one interface is being sent to the other interface which stops immediatley when I unsubscribe.

But try as I might the actual traffic does not flow thru the router.

I have tried quite a few examples off the web, none work for me.

Can I do it with a single 2821, I need 2 machines sending data to the same MC address and one client to pick out the MC data using an SSM IGMPv3 message.

I was hoping someone had a similar system from one of the labs, and they could just dump a config.
