Best method to load balance between two MPLS legs

[Brian Aeschliman]

At our plant we have a ISP who could not bond more than 10 MB, and we required 12 MB of service. The ISP had brought in another leg of service, which gave use two 6 MB links that went into our MPLS cloud. We push OSPF into this MPLS cloud which allows us control over the routing. We have 3 other remote sites connected to this MPLS cloud. Our situation is that we can't seem to get the traffic to load balance properly on the two legs at our head office. The traffic seems to prefer using one leg or the other for the majority transmissions, and the opposite leg then assumes the duty of being the main recieve leg. I have setup the OSPF to do per packet load balancing. When I perform a traceroute the traffice seems to move form one multilink to the other in the correct fashion, but our network moitoring software shows a different story. Does anyone have any other suggestions as to how I can better manage the flow of traffic into and out of the MPLS?

If your Cisco supports it, you might want to look at PfR with PIRO.

PS:

Would recommend NOT to use packet-by-packet load balancing.
