Hi San,

virtual template interface are used to combine multiple interfaces in to one virtual interface called virtual template, assume that you have you hav two 2 Mbps link & you wanted to combine in to 1 virtual link as 4 Mbps, virtual interface will do the needful, go through the configuration below, which is working configuration, which i hav already posted today.

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

ip vrf forwarding customer

pvc 101/52

but what is difference between virtual template int and multilink int

Hi San,

A Virtual Template Interface Service feature provides a generic service that can be used to apply predefined interface configurations (virtual template interfaces) in creating and freeing virtual access interfaces dynamically, as needed.

A virtual template interface is a logical entity?a configuration for a serial-interface but not tied to a physical interface?that can be applied dynamically as needed. Virtual access interfaces are virtual interfaces that are created, configured dynamically (for example, by applying [cloning] a virtual template interface), used, and then freed when no longer needed.

Hi,

The Multilink interface was introduced in Cisco IOS Software Release 12.0(3)T.

A multilink group interface is a collection of interfaces bundled together in the multilink PPP configuration, accordingly with a multilink group interface, you can bundle interfaces into logical multilink groups.

Multilink interface supports only PPP encapsulation.

when I give  inside Virtual Template this command it gives me error, (PPP Multilink)

this is the error message

DWNLD_TO_CPP_FAILED: F0: fman_fp_image:
MLP bundle  download to CPP failed

any idea ?
