A system (510) routes packets in a network (200) having multiple nodes. The system identifies a group (500) of the nodes (520 550) and determines routing distances to each of them. The system (510) then selects a set of the nodes from the group (500) based on the determined routing distances and updates a routing table based on the selection. The system (510) routes packets through the network (200) using the updated routing table.
