I have a solaris 9 system on Sparc. I am using it as a router between my 10.x.x.x network and the 192.x.x.x network. I am multicasting content from servers on 192 network to clients on the 10 network.

My solaris system shows both interfaces enabled for MULTICAST and the route for multicasting, namely, 224.0.0.0/4 is also shown in `netstat -nr` with 10. interface as the gateway.

When I snoop, I can see it receiving packets on the 192 interface but nothing goes out the 10 network.
What am i doing wrong?


If there are routers on the 10 dot network you might have to configure them to forward Join and Leave commands that are generated from the endsystems. But setting that issue aside for a moment, you first should check that your endsystems are in fact sending IGMP Join commands. I don't recall what those packets look like but most packet sniffers (i'm thinking of ethereal in particular) can detect them. So that's the first question: Does your sniffer see IGMP Join packets? The second question is: Can you determine that those packets are indeed getting into the 192 dot network or at least as far as the 192 interface?
