Associating a VPN instance with an interface
After creating and configuring a VPN instance, you must associate the VPN instance with the interface
connected to the CE. Any LDP-capable interface can be associated with a VPN instance. For information
about LDP-capable interfaces, see
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.
NOTE:
The ip binding vpn-instance command deletes the IP address of the current interface. You must
re-configure an IP address for the interface after configuring the command.
Configuring route related attributes for a VPN instance
The device processes VPN route advertisement as follows:
When a VPN route learned from a site 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 site.
The VPN instance determines which routes it can accept and redistribute according to the
•
import-extcommunity in the route target.
The VPN instance determines how to change the route targets attributes for routes to be advertised
•
according to the export-extcommunity in the route target.
IMPORTANT:
Create a routing policy before associating it with a VPN instance. Otherwise, the device cannot filter the
routes to be received and advertised.
To configure route related attributes for a VPN instance:
Step
1. Enter system view.
2. Enter VPN instance view.
3. Enter IPv4 VPN view.
4. Configure route targets.
