Configuration prerequisites
Before you configure basic MPLS L3VPN, perform the following tasks:
• Configure an IGP for the MPLS backbone (on the PEs and Ps) to achieve IP connectivity.
• Configure basic MPLS for the MPLS backbone.
• Configure MPLS LDP for the MPLS backbone so that LDP LSPs can be established.
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 besides MPLS L3VPNs.
All VPN instance configurations are performed on PEs.
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:
