[c-nsp] ASR 901 MPLS issues

[Jerry Bacon]

I'm trying to get an ASR 901 (IOS 15.4(2)S1) to do simple EoMPLS with a 
6500 (IOS 15.1(2)SY).

A port level xconnect works just fine. However, when I try to do a VLAN 
xconnect, I only get traffic (actually just MACs) in one direction, from 
the ASR to the 6500. It doesn't appear that I get anything back at all, 
even though the xconnect comes up and all looks normal there. Any ideas?
