Hello colleagues.
We are trying to configure mldp-based mvpn in our mpls network (6500 with sup720-3C and 2T). But we have the problem: no multicast traffic at receiver PE from mdt data.
I'm sure that our streamers are OK, because R1-source has STBs connected to it (behind SVI vlan16) and these STBs get multicast.
Have you any ideas why we can't get multicast at R2 ?
Here are outputs of commands:
