Figure E-11 VPLS EWS Topology
The Ethernet Relay Service (ERS or EVP-LAN) offers the any-to-any connectivity characteri stics of EWS and the service multiplexing. This combination enables a single UNI to support a customer's intranet connection and one or more additional EVCs for connection to outside networks, ISPs, or content providers. Figure E-12 illustrates an ERS (EVP-LAN) VPLS multipoint topology.
