Generalized Multiprotocol Label Switching (GMPLS) External Network Network Interface (E-NNI): Virtual Link Enhancements for the Overlay Model

Generalized Multiprotocol Label Switching (GMPLS) External Network Network Interface (E-NNI): Virtual Link Enhancements for the Overlay Model This memo is a companion document to [RFC4208]. It describes how the client domain networking in the overlay model can be enhanced via presenting to the client the network domain as an overlay topology made of Virtual TE Links.
