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: http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/fsstitch.html 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: http://www.juniper.net/us/en/local/pdf/whitepapers/2000279- 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. http://www.metroethernetforum.org/PPT_Documents/Overview%20of%20MEF26.ppt Hope this helps. Cheers, Mark.
