Abstract: In one embodiment, a method comprises identifying, by a network device operating in a network topology as a directed acyclic graph (DAG) root, a source-route path for reaching a destination device in the network topology; determining whether one or more parent devices along the source-route path between the network device and the destination device are capable of storing a route entry specifying routing information for reaching the destination device; and causing installation of a route entry for reaching the destination device in one or more of the parent devices determined as capable of storing the corresponding route entry.
