Configuring VPN instances
By configuring VPN instances on a PE, you isolate not only VPN routes from public network routes,
but also routes between 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:
Step
