2.2 VPLS Basic Function Configuration

2.2.1 VPLS Overview

There are some VPLS terms,
l
Access Circuit (AC)
It is a link between user and service provider, that is to say, the connection between
CE and PE. Ethernet interfaces are usually used in access circuit.
l
Pseudo Wire (PW)
It is a bidirectional virtual connection between Virtual Switch Interfaces (VSI) on a pair
of PE devices. It is composed of a pair of unidirectional MPLS Virtual Circuit (VC) with
opposite direction. It is also called emulation circuit.
l
TAG
TAG is added by service provider to distinguish users. It is called Service Delimiting
(SDT), also called PTAG.
VPLS working principle is shown in
