ive got a pair of routers with an OSPF and PIM adjacency between them and two workstations on either side. I'm trying to push multicast video across them using vlc as a source on one workstation and a reciever on the other. I cannot use anything other than PIM sparse ASM, and I choose to use a staticly configured RP on both routers. I can see the reciever 'igmp join', but the source never seems to register for the group. show ip mroute has the correct out going interfaces on both routers and the correct incoming int on the second router but the incoming interface on the first router is null. Is there something im missing?
Did you check the TTL is 5 on the packet using wireshark because I had a problem where VLC was always sending packets with TTL=1 even after setting it to >1 in the software.
Just my 2 cents.
