Configuration prerequisites

Before you configure basic MPLS L3VPN, perform the following tasks:
1. Configure an IGP on the PEs and P devices to ensure IP connectivity within the MPLS
backbone.
2. Configure basic MPLS for the MPLS backbone.
3. Configure MPLS LDP on the PEs and P devices to establish LDP LSPs.

Configuring VPN instances

VPN instances isolate VPN routes from public network routes and routes among VPNs. This feature
allows VPN instances to be used in network scenarios in addition to MPLS L3VPNs.
All VPN instance configurations are performed on PEs or MCEs.
Creating a VPN instance
A VPN instance is a collection of the VPN membership and routing rules of its associated site. A VPN
instance might correspond to more than one VPN.
To create and configure a VPN instance:
