instance.
4. Configure a description for
the VPN instance.
Associating a VPN instance with an interface
After creating and configuring a VPN instance, 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 "Configuring basic MPLS."
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.
To configure route related attributes for a VPN instance:
Step
1. Enter system view.
2. Enter VPN instance view.
3. Enter IPv4 VPN view.
