Abstract
In one embodiment, a method includes identifying a change in network topology at a network device, transmitting a test packet from the network device to determine if an adjacent network device located in a backup path has converged following the network topology change, and updating a forwarding information base at the network device in response to the network topology change if a response to the test packet indicates that the adjacent network device has converged. An apparatus and logic are also disclosed herein.
