Configuring VPN instances
VPN instances isolate not only VPN routes from public network routes, but also 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 or MCEs.
Creating a VPN instance
A VPN instance is associated with a site. It is a collection of the VPN membership and routing rules of its
associated site. A VPN instance does not necessarily correspond to one VPN.

Step
1. Enter system view.
2. Create a VPN instance and
enter VPN instance view.

instance.
