Did you check the IGMP version used on your PC and on the router?

Subject: multicast testing with videolan application
Hi all,
I've just started studying multicast routing, and am using Videolan to
test various scenarios. At the moment I am just looking at a simple
dense-mode setup with 2 routers, a switch and 2 XP PC's. I set up one
PC to broadcast using the multicast IP 239.20.30.40, the other to
receive it. I then configured dense mode multicast on the routers. I
could see the above group on the receivers router when I ran show ip
igmp groups. However the streaming PC didn't seem to make any attempt
to join the same group on the router attached to it. The only way I
could get it to work was to configure the ip igmp join-group command
on the interface attached to the server. Once this was configured, it
worked fine.
I thought the ip igmp join-group command was basically a debugging
tool, used to make the router respond to multicast pings etc. Why was
this command needed? Has any else seen this when using Videolan? Am I
missing something wiht regard to configuring dense-mode multicast?
Thanks again
Roy
