You should be able to alter the cost of route you want not to be taken primarily. Increasing it's cost to more than the other one would get you desired results.

Thanks.

"Would I change the bandwidth settings on the hub router interfaces . . ."

You could if auto costing was active.

". . . or is there another way to do this?"

Answered in other posts, but you sometimes need to be cautious what values you use for explict costing. For instance, setting cost to 1 indicates the best absolute link cost, but since end-to-end cost are cumulative, you want to avoid situation where part of your LAN decides the best path is via a branch. You also have to watch for wrapping the OSPF cost.

Also, if you looked to see if the link was already auto costed, and the assigned cost value (sh ip os in), you would only need to change one of the two interfaces to be better or worse than the other.

PS:

Besides the above, what prompted me to write was being curious about your question. Usually the question, for your described topology, is the converse, i.e. how do you use both links from the branch to the hub. Is there a reason why you want primary/secondary rather than use both links?
