Load Balancing traffic equally over Multilink

[Ashish Shah]

Hi,

I have a querry regarding sharing traffic equally on all the E1's attached in Multilink.

In my setup I'm running with two routers and a P2P link between them. I have a bundeled 4 E1's into Multilink. My querry here is when I check the traffic flow I observe 1 or 2 E1's as highly utilized where as rest minimal utilized.

Is there any way that I can configure and share traffic equally on all the E1's and utilize them properly.

Waiting for reply.

Thanks!

One of the features of multilink is that it shares traffic over the members of the multilink bundle and should result in proportional amounts of traffic. If you are seeing some links very much used and some links not much utilized then it looks like there is some problem. I believe that there are a couple of things that you could check:

- is there some configuration difference between the highly used links and the lightly used links (especially anything that would make it look like there is different bandwidth between the interfaces).

- are there errors on the less used serial interfaces?

If those suggestions are not helpful then it would be helpful if you would post the output of show interface for the multilink and for the individual serial interfaces and the output of show ppp multilink.

It might also help if you would post the configuration of the multilink and the individual serial interfaces.
