Introduction
This document provides VPLS configuration examples.
Virtual Private LAN Service (VPLS) delivers point-to-multipoint L2VPN services over an MPLS or IP backbone. The provider backbone emulates a switch to connect all geographically dispersed sites for each customer network. The backbone is transparent to the customer sites, which can communicate with each other as if they were on the same LAN.
VPLS has two networking models: full mesh and H-VPLS.
The full mesh model supports the following signaling protocols:
· LDP—Applies to the scenario where customer sites are a few and fixed.
· BGP—Applies to the scenario where customer sites are many and new sites will be added.
The H-VPLS model supports the following access modes:
· LSP access—Applies to the scenario where the devices connected to customer sites support MPLS. In this mode, customer packets directly enter the LSP tunnel.
· QinQ access—Applies to the scenario where the devices connected to customer sites do not support MPLS. In this mode, customer packets are added with an outer VLAN tag before they enter the LSP tunnel.
Prerequisites
The configuration examples in this document were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.
This document assumes that you have basic knowledge of VPLS.
Example: Configuring LDP VPLS instances
Network requirements
As shown in Figure 1, a customer has three sites connected to different CEs and will not add new sites.
Configure LDP VPLS instances on the PEs so that the customer sites can communicate in VLAN 1000 over the MPLS backbone.

Requirements analysis
To establish public LSPs between PEs, enable MPLS and LDP on all PE and P devices.
To transmit private labels between PEs, create VPLS instances and specify the peer PEs as LDP peers on the PEs.
To differentiate private data, configure match criteria on the PEs' interfaces connected to CEs. In this example, configure a match criterion to permit packets with VLAN ID 1000 so that the customer sites can communicate within VLAN 1000 over the MPLS backbone.

Example: Configuring BGP VPLS instances
Network requirements
As shown in Figure 1, a customer has three sites connected to different CEs and will add new sites.
Configure BGP VPLS instances on the PEs so that the customer sites can communicate in VLAN 1000 over the MPLS backbone.

Requirements analysis
To establish public LSPs between PEs, enable MPLS and LDP on all PE and P devices.
To transmit private labels between PEs, create VPLS instances and specify the peer PEs as VPLS address family BGP peers on the PEs.
To differentiate private data, configure match criteria on the PEs' interfaces connected to CEs. In this example, configure a match criterion to permit packets with VLAN ID 1000 so that the customer sites can communicate within VLAN 1000 over the MPLS backbone.

This configuration example was created and verified on S12500-CMW520-R1825P01.

Example: Configuring H-VPLS with LSP access
Network requirements
As shown in Figure 3, a customer has three sites connected to different CEs.
Configure H-VPLS with LSP access so that the three sites can communicate in VLAN 1000 over the MPLS backbone, and configure PW redundancy to improve link availability.

Requirements analysis
To establish public LSPs between PEs, enable MPLS and LDP on all PE and P devices.
To transmit private labels between PEs, create VPLS instances and specify LDP peers on the NPEs and UPE, and bind the VPLS instance to the receiving interface and VLAN on the UPE.
To differentiate private data, configure match criteria on the PEs' interfaces connected to CEs. In this example, configure a match criterion to permit packets with VLAN ID 1000 so that the customer sites can communicate within VLAN 1000 over the MPLS backbone.
To improve link availability, configure the UPE to establish a primary PW to NPE 1 and a backup PW to NPE 2. When the primary PW fails, the backup PW is used to forward VPN traffic.
Software version used
This configuration example was created and verified on S12500-CMW520-R1825P01.
Configuration procedures
This example only shows the H-VPLS with LSP access configuration between Site 1 and Site 2. Follow the same steps to configure H-VPLS with LSP access between different sites.

Example: Configuring BFD for H-VPLS
Network requirements
As shown in Figure 4, a customer has three sites connected to different CEs, and often uses voice or video services.
Configure H-VPLS so that the three sites can communicate in VLAN 1000 over the MPLS backbone, and configure BFD for H-VPLS to ensure fast link failover.

Requirements analysis
To establish public LSPs between PEs, enable MPLS and LDP on all PE and P devices.
To transmit private labels between PEs, create VPLS instances and specify LDP peers on the NPEs and UPE, and bind the VPLS instance to the receiving interface and VLAN on the UPE.
To differentiate private data, configure match criteria on the PEs' interfaces connected to CEs. In this example, configure a match criterion to permit packets with VLAN ID 1000 so that the customer sites can communicate within VLAN 1000 over the MPLS backbone.
To ensure high link availability for voice and video services, configure the UPE to establish a primary PW to NPE 1 and a backup PW to NPE 2, and configure BFD on the primary PW. When the primary PW fails, VPN traffic can be quickly switched to the backup PW.
Software version used
This configuration example was created and verified on S12500-CMW520-R1825P01.
Configuration procedures
This example only shows the H-VPLS configuration between Site 1 and Site 2. Follow the same steps to configure H-VPLS between different sites.

Example: Configuring hub-spoke VPLS
Network requirements
As shown in Figure 5, a customer has four sites connected to different CEs.
Configure hub-spoke H-VPLS so that the sites can communicate in VLAN 1000 over the MPLS backbone, and the spokes Site 1, Site 2, and Site 3 communicate with each other through the hub Site 0.

Requirements analysis
To establish public LSPs between PEs, enable MPLS and LDP on all PE and P devices.
To transmit private labels between PEs, create VPLS instances, specify the Hub-PE as an LDP peer, and specify the type of the PW to the Hub-PE as Hub on the Spoke-PEs; create VPLS instances, specify the Spoke Hub-PEs as LDP peers, and specify the type of the PWs to the Spoke-PEs as Spoke on the Hub-PE.
To differentiate private data, configure match criteria on the PEs' interfaces connected to CEs. In this example, configure a match criterion to permit packets with VLAN ID 1000 so that the customer sites can communicate within VLAN 1000 over the MPLS backbone.
