Abstract
In one embodiment, a method includes detecting a change in network topology and broadcasting a transient unconditional unpruning message to all nodes in the network. The message is configured to instruct each network element receiving the message to start a phase timer in response to the broadcast message; unprune its operational ports; and, upon expiration of the phase timer, prune its ports in accordance with the results of a pruning protocol.
