Configuring nested VPN
Network requirements
The service provider provides nested VPN services for users, as shown in Figure 65.
• PE 1 and PE 2 are PE devices on the service provider backbone. Both of them support the nested
VPN function.
• CE 1 and CE 2 are connected to the service provider backbone. Both of them support VPNv4
routes.
• PE 3 and PE 4 are PE devices of the customer VPN. Both of them support MPLS L3VPN.
