Interconnecting three or more sites across a metro or wide area network has traditionally been accomplished via a hub and spoke network topology using Private Lines, Frame Relay or IP VPNs over the Internet. Ethernet services support hub and spoke topologies but also support an “any-to-any” network topology similar to a LAN but delivered over a wide area. This latter capability is unique to Ethernet services and cannot be cost effectively delivered using legacy point-to-point technologies such as Frame Relay or IP VPNs.

This paper discusses two options for multi-site connectivity using Ethernet services. One option discusses the classical hub and spoke topology using Ethernet Virtual Private Lines (EVPL). The other option discusses the “any-to-any” topology using an Ethernet Private LAN (EP-LAN) service. Through examples, the paper illustrates the capabilities of the two approaches and their benefits.
