OK, I misunderstood Pete, regarding "port mode" and "vlan mode" EoMPLS.

What you can do is:

  int g3/7
    xconnect 1.2.3.4 5 enc mpls

or

  int g3/8
    encaps dot1q 23
    xconnect 1.2.3.4 6 enc mpls

but indeed, configuring EoMPLS on an "int vlan" won't work.

This is what I had in mind.

sorry for the confusion,
