The penalty command is the primary tool for configuring open-loop optimization parameters.
For open-loop optimization, the decision-maker process obtains all of the data needed to evaluate the link from sources other than the link itself.
See Figure 1.
The value you set with the penalty command is added to the metric calculated from traffic measurements when determining which links should be included in the winner set, and therefore which routes should be asserted as best performance routes.
The penalty command is entered in the link configuration block.
The higher the penalty, the less likely the link will be in the winner set and therefore the less likely it will be asserted as the best performance route to a particular prefix. By adjusting penalty settings among all of your links, you can express a preference for or against a particular link under all circumstances without regard to current traffic distribution (either for all prefixes, or for specified prefixes).
