As shown in Figure 6-4, the UPEs add double MPLS labels to packets sent by CEs. The outer

layer is a static LSP label and is switched when a packet passes through the devices on the access

network. The inner label is a VC label that identifies a VC. The inner label remains unchanged

when a packet is transmitted along the LSP. Packets received by an SPE contain double labels.

The outer label, which is a statically configured public network label, is popped up. The inner

label determines the VSI which the SVC accesses.

Inter-AS VPLS

Martini and Kompella VPLSs can implement inter-AS Option A. In the inter-AS VPLS

networking, the type of links between Autonomous System Boundary Routers (ASBRs) must

be the same as the type of VCs. If the number of inter-AS VCs is small, Option A can be used.

6.3 Configuring Kompella VPLS

This section describes how to use BGP as the VPLS signaling to configure Kompella VPLS and

how automatic discovery of VPLS PEs is implemented by configuring VPN targets..
