When the host joins on loopback interface, igmp daemon is expected to receive the join report on loopback interface. Here the join on loopback interface is not going outside the PC(Outside Network). Is it possible to receive join report (@ igmp daemon) with source IP address as loopback interface address in above explained setup? When I run the host, output of netstat command is as below: #netstat -ng IPv6/IPv4 Group Memberships Interface RefCnt Group --------------- ------ --------------------- lo 1 239.5.1.7 ==========> This is the group joined on loopback lo 1 224.0.0.1 eth0 1 224.0.0.1 eth0 1 239.5.5.6 eth0 1 239.5.5.7 Please cc me in the response Regards, Anupam
