These routes are taken from VPN routing and forwarding instances (VRFs), with which customer sites are associated. The population of these forwarding tables is achieved through advertisement of VPN routes across the backbone network, as discussed in Chapter 9, "MPLS/VPN Architecture Operation," and also from the receipt of routing updates from attached customers (or through static routing).
