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.
