Hello Experts,
I was configuring an INE full scale lab for the CCIE preparation and I faced the following problem with Multicast.
The idea is to have multicast traffic being R3 the source, R9 the receiver and R7 the RP. The ISP (R4, R5) are not multicast capable and a tunnel has been established between R1 and R6. I could not make it work and since I had some doubts regarding my MP-BGP configuration I narrowed down the problem to make the source R6.
On R7 the ip of the RP is advertised to R6, and on R6 the ip of the source is advertised to both R7 and R8. At the end the scenario is fair simple Multicast across ASN 65006 and 65087. I used BSR to advertise RP reachability. R6 gets this information but the multicast traffic does not work.
I set up a couple of packet captures on the link R6-R7 and R6-R8. Interestingly I an see the traffic (an ICMP to 230.1.3.10) but did not see the PIM register from the source to the RP. I would expect that the first packet is encapsulated inside a unicast packet, but this is not the case. I have no idea what is misconfigured.
Here the configs
