Summary:The method of the present invention provides efficient aggregation of link metrics for a subnetwork in a communication network having a plurality of interconnected subnetworks that consist of nodes and links. The method includes: selecting, by a predetermined subnetwork leader, a subset of nodes in the subnetwork to be exposed nodes; for each link metric, generating, by the subnetwork leader, a spanning tree virtual topology connecting the exposed nodes; and assigning link metric values to the virtual links on the spanning tree and advertising the metric values in a topology broadcast by the subnetwork leader.
