A computing device ranks multiple routing pairs based on a current routing configuration for weighted links in a network, and ranks the multiple routing pairs based on a proposed routing configuration, different than the current routing configuration, for the weighted links in the network. The computing device compares a current rank order of a first routing pair and a second routing pair in the multiple routing pairs with a proposed rank order of the first routing pair and the second routing pair. The computing device identifies a change between the current rank order and the proposed rank order and generates a data structure that indicates the identified change between the current rank order and the proposed rank order for the first routing pair and the second routing pair.
