Example for Configuring Nested VPN
Network requirements
The service provider provides nested VPN services for users, as shown in Figure 1-24 , where:
z
PE 1 and PE 2 are PE devices on the service provider backbone. Both of them support the nested
VPN function.
z
CE 1 and CE 2 are connected to the service provider backbone. Both of them support VPNv4
routes.
z
PE 3 and PE 4 are PE devices of the customer VPN. Both of them support MPLS L3VPN.
z
CE 3 through CE 6 are CE devices of the sub-VPNs for the customer VPN.
The key of nested VPN configuration is to understand the processing of routes of sub-VPNs on the
service provider PEs, which is described as follows:
