Static VPLS Service Mapping Configuration
Overview
This chapter includes step-by-step configurations for static VPLS. It also contains an overview of the concepts of Static VPLS. Virtual Private LAN Service (VPLS) is a way to provide Ethernet-based multipoint-to-multipoint communication over IP- MPLS networks. It allows geographically-dispersed sites to share an Ethernet broadcast domain by connecting sites through pseudowires.
Topology
The diagram depicts the topology for the configuration examples that follow.
