VPLS Accessing L3VPN

VPLS Accessing L3VPN

On the network shown in Figure 9-6, the NPE functions as the PE of both the access network and the bearer network. In addition to VPLS, the NPE needs to support the gateway function, including the configuration of IP addresses, access to L3VPNs, ARP, and packet forwarding.

When a CE needs to access the L3VPN, the CE sends an ARP request to the gateway interface of the NPE. The NPE then forwards traffic between the L2VPN and L3VPN. Meanwhile, the traffic forwarding on the original L2VPN is not affected. The NPE needs to broadcast ARP packets locally and in the VSI.
