Abstract
A method includes generating a first shortest path tree for traffic routing in a network, the first shortest path tree identifying a corresponding shortest path from the network node to other nodes in the network and generating a second shortest path tree for traffic routing after removing an element from the network. The second shortest path tree identifies a corresponding shortest path from the network node to the other nodes in the network with the element removed. A third shortest path tree is generated, which is a weighted version of the second shortest path tree with a weight value added to any node or link in the network sharing a SRLG value with the element removed from the network. Network traffic is enforced based on a comparison of the third shortest path tree with at least one of the first shortest path tree and the second shortest path tree.
