I configured the router which are connecting to 2 different branches. But always i can see the traffic is flowing only through one link only. how can i do a load balancing. The 1st link is 128Kbs and second is 64Kbs. Is it necessay that both the links should be in same band width.

Hi


Is the links going to the same destination,if they are then load-balancing will take automatically if u have specified routes with equal AD.


Thanks

Specifying equal AD only specifies that both routes were learned from the same protocol source (both statics, or both OSPF, or both EIGRP, etc). Whether load balancing occurs or not depends on the routing protocol. If running OSPF there would not be load balancing because the OSPF metric is calculated from bandwidth and OSPF does not support un-equal cost load balancing. If running EIGRP there is an option to specify variance and EIGRP can support load balancing over un-equal cost paths. If the links are both one hop away then running RIP or configuring static routes can do load balancing because both paths will look equal.

Thank you for the kind words. I am pleased to be an asset to the forum. Early in my career I did not understand many of these things nearly as well as I do now. I am pleased to see your responses in the forum and hope that you will continue your studies, continue to improve your understanding of these concepts, and continue to be active in the forum.

Little bit confused with ur query above, would like you to brief the setup once again. I understand that u have a rouer A conntected to two barances B and C, how the two link in picture are connected are they pointing to one location either B or C.


Also brief us what routing protocol u r using for the same


Thanks EM
