Abstract
In one embodiment, a method comprises creating, in a computing network, a loop-free routing topology for reaching a destination device, the loop-free routing topology comprising distinct paths for reaching the destination device; generating a set of serialized representations describing the loop-free routing topology, each serialized representation describing a corresponding one of the paths; and propagating the set of serialized representations from the destination device to network nodes in the computing network, enabling the network nodes to establish loop-free label switched paths for reaching the destination device via the loop-free routing topology.
