Virtual Template Interfaces Limit Expansion


First Published: October 15, 2001
Last Updated: February 28, 2006

The Virtual Template Interfaces Limit Expansion feature allows you to increase the maximum number of virtual template interfaces. Prior to this feature, the maximum number of virtual template interfaces allowed was only 25. This feature allows you to have up to 200 virtual template interfaces. A higher number of virtual template interfaces is required for configuring virtual private network (VPN) routing and forwarding (VRF) applications when you want to associate each virtual private dialup network (VPDN) customer to a VRF.

Usage Guidelines

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 non volatile random access memory (NVRAM).

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

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

Examples

The following example creates and configures virtual template interface 1:

interface virtual-template 1
 ip unnumbered ethernet 0
 ppp multilink
 ppp authentication chap
