Abstract: In one embodiment, a method comprises creating, in a computing network, a hierarchal routing topology for reaching a destination, the hierarchal routing topology comprising a single parent supernode providing reachability to the destination, and a plurality of child supernodes, each child supernode comprising one or more exit network devices each providing a corresponding link to the parent supernode; receiving, in one of the child supernodes, a data packet for delivery to the destination; causing the data packet to traverse along any available data link in the one child supernode independent of any routing topology established by network devices in the one child supernode, until the data packet reaches one of the exit network devices; and the one exit network device forwarding the data packet to the parent supernode, via the corresponding link, for delivery to the destination.
