Load balance over unequal paths

[thomuff]

Location A is connected to Location B via a T1 connection with router a-1 and router b-1 and a A 768kb Frame relay Pvc with router a-2 and router a-2. To use both paths at the same , I would have to run EIGRP as my IGP, correct?? Currently, we are running OSPF.

Yes, I believe you are correct. EIGRP and IGRP are the only routing protocols that support unequal cost load balancing. You will have to use the variance command.

For OSPF, check out the "ip ospf cost" interface command:

With EIGRP/IGRP you would use the "variance" feature:

Here's a general document about how load-balancing works in IOS:

Hi,

Load balance via a routing portocal like eigrp is possible only if

1: both the links have the same cost

2: both the links are in the same router

If you want to to do load balancing over uequal paths then this can be done using inverMUX or with policy routing, or if you want to try you can also use CEF. with the command line "ip cef" global command and "ip load-sharing per-packet in the interface "

Please note that all this can be done only if both the links are of equal cost.

other wise split the traffic based on tcp ports using policy routing

thanks
