VPLS Configuration Example
This section will demonstrate how to set up a Service Distribution Point (SDP) between two far-end hosts
and bind a VPLS instance to the SDP.
• Label Distribution Protocol (LDP) signaling is enabled on the adjacent router interfaces to set up the
Label Switched Paths (LSPs) between the routers. See Chapter 10, “Configuring MPLS,” for more
information.
• Example configuration steps assume that the IP and routing functionality is available, configured and
enabled.
• The label information distributed between the peers and the tunnel setup is included.
• The messages and databases (FEC, VC labels) updated as a result of the LSP's are also included.
The illustration below shows the example VPLS configuration described in this section. In this configura-
tion, the provider edge bridges will encapsulate customer traffic tagged with VLAN ID 100 into VPLS
service 100. The customer traffic is then transparently bridged through the service and sent out to the
destined customer site.
