Associating a VPN Instance with an Interface
In an MPLS L3VPN application, you need to associate VPN instances with the interfaces
connecting the PEs.
In a tunneling application, you need to associate VPN instances with the tunnel interfaces
connecting the peer MCE devices or CE devices.

connecting different VPN sites.
Follow these steps to associate a VPN instance with an interface:
To do...
Enter system view
Enter interface view
