As far as I know, EIGRP is the only IGP which support unequal loadbalancing,in another wrod, you can not achieve unequal loadbalancing by using OSPF.

OSPF will load balance two paths with exact the same metric by default. In addition you need to check your CEF load balancing, which is deciding, which traffic goes through which link if both paths are in the routing table.

The default is "per destination" but can be changed to "per packet". So a traffic analysis might help to understand the different load on the two links.

Hello,

OSPF is calculating the cost of the links to a destination network based on the bandwidth of the links. Since you asked for unequal load balancing I suppose they have the same bandwidth and load balancing is performed. With OSPF it's difficult to achieve this scenario but I think you can use MPLS TE to forward the traffic unequally on similar links. And you can use policy-based routing (PBR) that allows for route selection based on user-defined policies, which is applicable in load balancing scenarios.

And EIGRP is not supported on Huawei devices, right ? It is Cisco proprietary protocol.
