Hi,
I am running a host application which joins multicast group on
loopback interface.
But the source IP address of IGMPv3 report is not loopback address (127.0.0.1).
Its picking up first available N/W interface address.
Snippet:
mreq.imr_multiaddr.s_addr = inet_addr("239.5.1.7");
mreq.imr_address.s_addr = htonl(INADDR_LOOPBACK);
mreq.imr_ifindex = 1; (Interface index of loopback)
check(setsockopt(s, IPPROTO_IP, IP_ADD_MEMBERSHIP, &mreq, sizeof(mreq)) == 0);
Is there any reason why loopback address is not source IP address of
join message?
Regards,
Anupama
