Associating a VPN instance with an interface
After creating and configuring a VPN instance, you need to associate the VPN instance with the interface
for connecting the CE. Any LDP-capable interface can be associated with a VPN instance. For
information about LDP-capable interfaces, see the chapter "Configuring basic MPLS."
To associate a VPN instance with an interface:
To do...
Enter system view
Enter interface view
Associate a VPN instance with the
interface
NOTE:
The ip binding vpn-instance command clears the IP address of the interface on which it is configured. Be
sure to re-configure an IP address for the interface after configuring the command.
Configuring route related attributes for a VPN instance
The control process of VPN route advertisement is as follows:
• When a VPN route learned from a CE gets redistributed into BGP, BGP associates it with a VPN
target extended community attribute list, which is usually the export target attribute of the VPN
instance associated with the CE.
The VPN instance determines which routes it can accept and redistribute according to the
•
import-extcommunity in the VPN target.
The VPN instance determines how to change the VPN targets attributes for routes to be advertised
•
according to the export-extcommunity in the VPN target.
To configure route related attributes for a VPN instance:
To do...
Enter system view
Enter VPN instance view
Enter IPv4 VPN view
