I'm not sure whether there is any real dedicated information 
on various forms of NNI at Layer 2 Ethernet other than it 
being a framework using general purpose protocols such as 
802.1Q, MPLS, IP, e.t.c.

There are interconnect standards for MPLS-based l3vpn's 
(Interprovider and CsC infrastructure). A Google should get 
you what you need.

Cisco have a feature called "L2VPN Pseudowire Switching" 
which supports MPLS-based NNI's for point-to-point l2vpn's:

Juniper also have a recommendation that provides for an NNI 
for VPLS between one domain running BGP for the control 
plane and the other running LDP:

en.pdf

Juniper also have other NNI implementations which use BGP 
that I can't share at this time. Would suggest contacting 
them if you're keen.

You might also want to check out what the MEF are doing 
under the MEF-26 specification.

Hope this helps.

Cheers,

Mark.
