Static VPLS Configuration
This chapter includes step-by-step configurations for Static VPLS. It also contains an overview of the concepts of Static VPLS.
Overview
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. A set of Martini circuits is grouped by a common VPLS identifier to achieve this service objective.
The VPLS identifier is exchanged with the labels, so that both PWs can be linked and be associated with a particular VPLS instance.
Configure Static VPLS
In the following examples, VPLS (v1) is configured on PE-2 with Static VPLS-Peers PE-1 and PE-3 using static LSPs.
