Configuring VPLS

Hardware compatibility

To run VPLS, an HP 10500 switch must use an EA, EB, SE, or SF card to connect the customer and
provider networks.

Overview

Virtual Private LAN Service (VPLS) provides point-to-multipoint L2VPN services over an MPLS or IP
backbone. The provider backbone emulates a switch to connect all geographically dispersed sites of
each customer network. The backbone is transparent to the customer sites and the sites can communicate
with each other as if they were on the same LAN.
