E-LAN (VPLS)

E-LAN (VPLS - Virtual Private LAN Service)...

E-LAN (VPLS – Virtual Private LAN Service) provides Virtual Private LAN Service, similar to LAN over MPLS network.A VPLS makes it possible to interconnect several LAN located in different places like they were one LAN. This technology extends the user LAN to MAN or WAN.

H-VPLS, Hierarchical VPLS is used to minimize the number of mesh pairs.

PE is divided into UPE (User Provider Edge), NPE (Network Provider Edge). The PW mapping varies with the hierarchy.

Common bridging types are Port and Port+VLAN.
