[c-nsp] Port-based EoMPLS treatment of l2protocol packets

That's correct..
"forwarded" l2protocols are incompatible with "tunneled" l2protocols

Actually there are differences among Cisco platforms in respect to their
ability to handle PDUs, which makes interoperability quite difficult some

The ME3400 can only tunnel
The ME3800x can tunnel and forward
The 7600 until recently could only forward. After the 15.3.1S version it
can also tunnel..
