Guys,
I have been stuck all day with this. For me it is so strange. I hope someone can help.
R1 -----Ethernet----- R2 --S0/0.24----------------------S0/0-R4

S0/0.256

Ether - R5 R6--- Ether
I am running Auto-RP with R2 as the RP and the Agent.
I configure mrm with R1 looback as the source and both R5 and R6 ethernet as recievers AT R2.
R5 is ok. It creats the (*.G) entry. It joins the shared treee. and it joins the SPT too. And it gets the muticast traffic with no problems.
R6 is a bit lose. From the debug i can tell that R6 creats the shared tree entry and it joins it successfuly. BUT it joins the SPT INTIALLY (when it recieve the FIRST multicast packet for the group)
Then (for some reason) it does't CONTINUE recieving the multicast traffic (ONE PACKET only is recieved for any group) . So it keeps counting down for the SPT entry and it prunes it eventually. And i stay with the (*,G) entry alone. And ofcourse no traffic is reaching the Ethernet behind R6 even when the SPT entry is still in the mroute table!!
The NBMA is running OSPF. I tried both default NMBA and multipoint options. In both cases all interfaces are reachable. But I get same problem with R6.
I tried two hardwares with two Different IOSs in R6 positon. Both gave the same symptons.
Can any one help!! (configurations r below)
Thanks
