Hi,
We have two ISP lease line and one Cisco ISR 2951 router. Can you let me know what are the configuration
so i can club the two ISP in our single 2951 router. So it will be load balacing the two ISP line.

There is no way. They are two seperate end points with no logical or physical relationship to each other.
you can do some load sharing

Like vmiller said it's not that easy to do any kind of aggregation of links. Can you share your NAT and static route config. You could setup multiple static routes that would at least load share the traffic but it's not really intelligent and takes no consideration to the different link speeds.

You need to provide more information. What kind of ISP lines do you have? What bandwidth are they? Are you running any dynamic routing protocol such as BGP? Are you running NAT?

Hi Daniel,
We are having two lease line 30Mbps and 45Mbps and we are doing static NAT and no dynamic routing.
We want to club this together so we will have 30+45 Mbps = 75 Mbps on our 2951 router.

If you are thinking multilink it probably won't work with the differing bandwidth.
Are your links provided by the same ISP ?

No we have different ISP

Thought so. Forget any form of link aggregation then.

So which one will be the best ... We just want to combine the two ISP that's all

Hi Vmiller and Daniel,
Thank you both for answering my doubt. A will try sharing NAT and static route config. You guys rock.
