I'm transporting multicast through a l3vpn with ME3600Xs, and the multicast VRFs are working, but so far only the default MDTs are working, that is, the multicast is getting broadcast to every node containing the VRF. I'd like to get data MDTs created to make the multicast distributin more efficient, so I configured this under the vrf config:
mdt data 18.104.22.168 0.0.0.255
I tried configuring a (low) threashold as well, but no data MDTs are being created for my test multicast streams. From what I've read that config line is all I should need for it to work, so I'm wondering what I'm missing, and how best to troubleshoot.
