Follow these steps to associate a VPN instance with an interface: 

Enter system view 

— 

Enter interface view 

interface interface-type 
interface-number 

— 

Associate the current interface 
with the VPN instance 

ip binding vpn-instance 
vpn-instance-name 

Required 

No VPN instance is associated 
with an interface by default. 

 

When configured on an interface, the ip binding vpn-instance command clears the IP address of the 

interface. Therefore, you must re-configure the IP address of the interface after configuring the 

command. 

 

The control process of VPN route advertisement is as follows: 

z 

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. 

z 

The VPN instance determines which routes it can accept and redistribute according to the 

import-extcommunity in the VPN target. 

z 

The VPN instance determines how to change the VPN targets attributes for routes to be 

redistributed according to the export-extcommunity in the VPN target. 

Follow these steps to configure route related attributes of a VPN instance 

Enter system view 

— 

Enter VPN instance view 

ip vpn-instance 
vpn-instance-name 

Required 

Associate the current VPN 
instance with one or more VPN 
targets 

vpn-target vpn-target&<1-8> 
[ both | export-extcommunity 
| import-extcommunity ] 

Required 

Configure the maximum 
number of routes for the VPN 
instance 

routing-table limit number 
{ warn-threshold | 
simply-alert } 

Optional 

The default varies by device. 

Apply an import routing policy 
to the current VPN instance 

import route-policy 
route-policy 

Optional 

By default, all routes permitted 
by the import target attribute 
can be redistributed into the 
VPN instance.
