Multiple multilink bundels

I have a requirement of configuring multiple ppp multilink bundles between two routers using virtual-templates. I cannot use Interface multilink because its not supported by the IOS. How can I configure it using multilink virtual templates and interface virtual-template

Re: Multiple multilink bundels

I assume you have a leased lines between two or multiple routers and wants to create multiple bundles..

First, two ways to bundle those links..Based on username and based on endpoint discriminator. Here is the link which explains which is the best in which condition..

You can refer to the sample config below, but remove "miltilink-group x" command under the t1 intreface and configure "intreface virtual-template 1" instead on "interface multilink x"

I can try explain it here.

Now lets say router has 4 links and you want to create two bundles with two links in each, you use config like this to create two bundles, one for username abc and other for username xyz with two links in each bundle.

remote router


int serial0

ppp chap host name abc

ppp multilink

int serial 1

ppp chap host name abc

ppp multilink

int serial2

ppp chap host name xyz

ppp multilink

int serial3

ppp chap host name xyz

ppp multilink

Central router


multilink virtual-template 1

multilink bundle-name authenticated endpoint

interfave virtual-template 1

ppp multilink

Make sure to include "ppp multilink" for all the serial interface on central router with other config.
