Some networks I have worked with took the average latency of each link and assigned that (with some constant multiple) as the interface cost.

Of course this all fails miserably if you are using anything like MPLS underneath your OSPF.

But then when using MPLS underneath, then MPLS Traffic Engineering can be used to do some interesting path computations and resiliency configurations.

I wasn’t attempting to promote or discourage use of MPLS. I was merely endeavoring to point out that in an MPLS world, OSPF costs are not how you want to manage your traffic. Owen
