Configuring a VPLS to Access the Public Network or an L3VPN

Configuring a VPLS to Access the Public Network or an L3VPN

This section describes how to configure VPLSs to access the public network or L3VPN. To achieve this, you can implement the VPLS technology on the access network.

Applicable Environment

As shown in Figure 10-5, a user has many scattered sites on the access network of a carrier, and they are connected through Ethernet. These sites are required to interconnect to form an integrated network. In this case, the VPLS can be deployed on the access network to network those sites, and to access the MPLS L3VPN service running on the bearer network. If there are many scattered sites on the access network, deploy the HVPLS on it, as shown in the access network 2 in Figure 10-5. The Network Provider Edge (NPE) works as Provider Edge (PE) at upper layer and UPEs as PE at lower layer. Therefore, the logical connections between PEs are reduced.

Pre-configuration Tasks

Before configuring a VPLS to access an L3VPN, complete the following tasks:

  • Connecting the interfaces and configuring their physical parameters so as to make their physical layer Up

  • Enabling IGP on the MPLS access network to realize IP connectivity

  • Creating full-mesh VPLS between UPEs and NPEs

  • Enabling IGP on the MPLS bearer network to realize IP connectivity

  • Configuring the basic functions of L3VPN on NPEs
