PPP Multilink Question

I was just wondering what the difference is between using:

1. interface Multilink x

and

2. Multilink virtual template x

inteface virtual-template x

commands to create a MLP. Currently, we have 2xT1 from one router to another router. I want to be able to combine the use of the 2 T1's to increase bandwidth and load balance.

Also, is it possible to create a VPN connection using bundled T1's?

Thanks in advance.

Re: PPP Multilink Question

In your case, use the interface multilink command.

interface multilink 1

ip address x.x.x.x y.y.y.y

encapsulation ppp

ppp multilink

multilink-group 1

interface serial 0

no ip address

encapsulation ppp

ppp multilink

multilink-group 1

interface serial 1

no ip address

encapsulation ppp

ppp multilink

multilink-group 1

ITS possible to create any sort of VPN connection through multilink interface. It just needs an Ip connectivity.

Re: PPP Multilink Question

Thank you for your response. I will try it. Also, is it recommended to disable fair-queuing on the Serial interfaces? Thanks again.

Re: PPP Multilink Question

It depends on the amount and type of traffic flowing on your serial interface. If you have ample bandwidth on your interface, you can as well disable it.
