[c-nsp] EoMPLS VC up on one side, not on the other.

[Stephen Fulton]

Thanks Stoffi, Oli..

The VLAN was SVI-based on the ME6524.  I've switched to VLAN-based, attached to 
the outgoing interface.. The VC is not coming up, so I've included a snippet 
below, in case I've missed anything.  Also, there is a name Cisco refers to 
adding a sub-interface for xconnect statements, while the main interface can be 
trunked for passing standard VLAN's.  For the life of me I cannot remember what 
it is.  Any ideas there?
