ITU-T G.8011.3 PDF

This Recommendation defines the service attributes and parameters for carrying Ethernet characteristic information over shared-bandwidth, multipoint-to-multipoint connections provided by SDH, ATM, MPLS, PDH, OTH, ETH or ETY server layer networks. This type of service is referred to as Ethernet Virtual private LAN (EVP-LAN) service. This Recommendation is based on the Ethernet service framework as defined in [ITU-T G.8011] and is aligned with the EVP-LAN services specified in [MEF 6.1].

This Recommendation specifies four attributes sets (EVC, EC, UNI and NNI) and values to describe an Ethernet Virtual private LAN service from the perspective of the network.
