you can select a virtual-template for the purpose of dynamic creation of virtual 
interface.

In VPN and MP application environments, the system automatically creates and 
deletes virtual interfaces, which is completely transparent to the user.

 The user 

only needs to configure VPN or MP on the involved physical interface, creates and 
configures a virtual-template, and finally associates the virtual-template with the 
physical interface.

Perform the following tasks to configure a virtual-template:

■

Create/Delete a virtual-template

■

Set operating parameters of virtual-template

■

Associate the virtual-template with the involved physical interface

Perform the following in the System View.

If the virtual-template that you intend to create by using the 

 command has existed, the system will directly enter the view 

of the virtual-template. Otherwise, the system will create the virtual-template 
assigned with specified number before entering its view.

In deleting a virtual-template, make sure that all of its derived virtual interfaces 
have been removed and this virtual-template is not in use any more.

Compared with a regular physical interface, virtual-templates only support PPP in 
terms of link layer protocol and IP and IPX in terms of network protocol. 
accordingly, you can perform the following tasks to set the following operating 
parameters:

■

Set PPP operating parameters

■

Assign an IP address to the virtual interface

■

Set the IP address (or IP address pool) assigned to the PPP peer

Setting these parameters on a virtual-template is the same as setting them on a 
regular interface.

You are required to associate an L2TP group with the virtual-template in a VPN 
environment and MP user with the virtual-template in an MP environment. 

For details, refer to Part X “VPN”.
