Current methods for traffic engineering with traditional link state routing protocols like OSPF and IS-IS are based on optimizing link weights to fit a given estimate of the traffic demands. These methods are not good at handling natural changes in the traffic over time. In this paper, we introduce new methods for IGP load balancing based on the upcoming standard for Multi-Topology routing. The main advantage of our approach is that it is far more robust to changes in the traffic demands. Our initial evaluations indicate that our method significantly reduces the chances of losing packets due to congestion.
