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.
A pseudowire (PW) consists of a pair of point-to-point, single-hop unidirectional LSPs in opposite directions, each identified by a PW label, also called a Virtual Connection (VC) label.
The Label Distribution Protocol (LDP) is used to signal constituent VCs, and the service provider may use either LDP or RSVP-TE or add static provisioning to set up LSP tunnels to transport data through virtual circuits.
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.
