Responded. If I did ping -I eth1 220.127.116.11 all nodes in the multicast
Group on eth1 responded. The ip_forward flag in proc was set to 1
And IP multicast routing and IP tunneling was set. I even installed
Mrouted but same result. I did not the Cisco PIM protocol which needs

What should the routing table on the router look like :
( unicast routing worked fine ).
126.96.36.199 0.0.0.0 255.255.255.255 eth0

( rest being same as above ).
Any tips on how to configure it correctly ?
