[c-nsp] Frame PVC -> 802.1q VLAN

I actually want to bridge raw IP packets , I know that sounds strange
but would be the terminology I would use when configuring IRB between a 
serial interface and an ethernet one (i.e Frame-Relay frames arriving on 
serial interface have their IP payload stripped out, and put in an 
ethernet frame and sent over the ethernet)
I'm reluctant to call it "routed" since no IP routing is taking place.

I didn't try L2VPN interworking (we use this already to achieve the same 
thing across the network) simply because I assumed that it would not 
work locally on the same box.

Having just tried it, I can confirm it does not work, allthough saying 
that the looped back pseudowire seems to have established itself:

I've two WAN circuits that I'd like to be able to interconnect with 
eachother in a location for a few weeks, one is delivered as frame relay 
NNI bundle and the other is a VLAN bundle over Gigabit Ethernet, neither 
circuit can be changed such that they are the same technology and the 
goal is to be able to use the bridged link to carry IP traffic on behalf 
of a service requiring a full IPv4 routing table (hence VRF out of the 
question).

Many thanks,

Dave.
