I have a l3vpn with vrfs and MPLS transport using 3600Xs. I'm trying to setup Multicast VPN, and I believe that I have the config right. I've turned on mcast for the vrf, turned on pim-ssm, I have a default mdt for the vrf etc. The problem is I can't seem to get multicast to travel from PE to PE. One quirk is that there are no CEs, the layer 3 gateways for the customer equipment are on the 3600Xs, so there is no PIM from a CE, there would just be streams coming into the PEs and IGMP joins. Is that setup problematic for multicast vpns?
That you for the reply Luc, that reminds me I had noted but forgot to mention the lack of PIM neighborship through the tunnel interface. Both 3600s have tunnel interfaces, both have ip pime sparse-mode configured on their loopbacks.
show ip mroute vrf
