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 "Configuring basic MPLS."
To associate a VPN instance with an interface:
Ste

Command Remarks
1. Enter system view.
system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Associate a VPN instance
with the interface.
ip binding vpn-instance
vpn-instance-name
No VPN instance is associated
with an interface by default.
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.

2. Enter VPN instance view.
ip vpn-instance vpn-instance-name

3. Enter IPv4 VPN view.
ipv4-family Optional.
4. Configure route targets.
vpn-target vpn-target&<1-8>
[ both | export-extcommunity |

A single vpn-target command can
configure up to eight route targets.
You can configure up to 64 route
targets for a VPN instance.
