Hi Radhika, It's not clear what is not working correctly. The encapsulation, the forwarding ? Also, please ensure that the interface you are forwarding to supports multicasting and you put the source address of the outgoing interface. Regards Kshitij

In my implementation, I want a multicast router to encapsulate multicast packets destined for certain groups with an extra IP header before forwarding them out. I am giving below some of the code: if(IN_MULTICAST(ntohl(ip->ip_dst.s_addr))) { struct in_multi *inm; if(ip_mrouter){ 1) Check if the destination address belongs to the group of packets that need to be encapsulated 2)calls my encapsulation function which returns an MBUF with the extra header 3)The encapsulated packet is then sent to ip_mforward } For some reason this does not seem to be working correctly, I would appreciate if someone can point out the mistake I am making here. Thanks a lot, Radhika __________________________________________________ Do You Yahoo!? Send FREE video emails in Yahoo!
