The virtual template interface is part of the Cisco Virtual Profiles dial feature.

With Virtual Profiles you can create and configure and later destroy a virtual access interface dynamically when a call is received or terminated.

For more information on configuring Virtual Profiles see http://www.cisco.com/en/US/products/sw/iosswrel/ps1828/products_command_reference_chapter09186a00800ca52f.html

Hi,

A virtual template interface is used to provide the configuration for dynamically created Virtual-Access interfaces. It is created by users and can be saved in nonvolatile RAM (NVRAM).

Once the virtual template interface is created, it can be configured in the same way as a serial interface.

To create a virtual template interface that can be configured and applied dynamically in creating virtual access interfaces, use the interface virtual-template command in global configuration mode.

Virtual template interfaces can be created and applied by various applications such as Virtual Profiles, virtual private dialup networks (VPDN), PPP over ATM, PPP over Frame Relay, protocol translation, and Multichassis Multilink PPP (MMP).

Following are FR and ATM examples:

interface Serial1/0.1 point-to-point

bandwidth 128

frame-relay interface-dlci 51 ppp Virtual-Template1

class FRTS

interface ATM1/0.52 point-to-point
