1.4.9 Nested MPLS L3VPN Configuration Example

I. Network requirements
A VPN user has multiple nodes to access the service provider's MPLS L3VPN
backbone network. And this VPN is divided into three sub-VPNs: VPN1, VPN2 and
VPN3.
Some of the nodes of these sub-VPNs directly access a PE in the network, and some
access a PE through the father VPN. That is, the adopted network structure is
unsymmetrical.
This example mainly describes the configuration of VPN1; the configuration of other
sub-VPNs is similar.
