Creating a VPN instance
You can configure a description for a VPN instance to record its related information, such as its
relationship with a certain VPN.
To create and configure a VPN instance:
Step
1. Enter system view.
2. Create a VPN instance and
enter VPN instance view.
3. Configure an RD for the VPN
instance.
4. (Optional.) Configure a
description for the VPN
instance.
NOTE:
To configure BGP for a VPN instance on the MCE, you must configure an RD for the VPN instance.
Associating a VPN instance with an interface
After configuring a VPN instance, you must associate the VPN instance with the interfaces connected to
the VPN site and the PE.
To associate a VPN instance with an interface:
Step
1. Enter system view.
2. Enter interface view.
3. Associate the current interface
with a VPN instance.
NOTE:
The ip binding vpn-instance command deletes the IP address of the current interface. You must
reconfigure an IP address for the interface after configuring the command.
Configuring route attributes for a VPN instance
The MCE controls VPN route advertisement as follows:
1. 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 list of the VPN
instance associated with the site.
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 attributes for a VPN instance:
Command
system-view
ip vpn-instance vpn-instance-name

Command
