Associating a VPN instance with an interface

After creating and configuring a VPN instance, associate the VPN instance with the MCE's interface
connected to the site and the interface connected to the PE.
To associate a VPN instance with an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Associate a VPN instance
with the interface.

Configuring route related attributes for a VPN instance

VPN routes are controlled and advertised on a PE by using the following process:
1. When a VPN route learned from a CE gets redistributed into BGP, BGP associates it with a route
target extended community attribute list, which is usually the export target attribute of the VPN
instance associated with the CE.
2. The VPN instance determines which routes it can accept and redistribute according to the
import-extcommunity in the route target.
3. The VPN instance determines how to change the route target attributes for routes to be advertised
according to the export-extcommunity in the route target.
To configure route related attributes for a VPN instance:
Step
1. Enter system view.
