Aspects of the present disclosure relate to synchronizing route updates. In one aspect, one or more computing devices, such as a router or a centralized controller, may receive a notification of a planned topology change to the network. The topology change may affect a link between nodes. Further, the one or more computing devices may determine one or more paths associated with the link and determine one or more user nodes associated with each path. The one or more computing devices may send an instruction message associated with the planned topology change to each user node of each path and receive an acknowledgment message in response to the instruction message. Based on the information in the acknowledgement message, the one or more computing devices may determine whether to effect the planned topology change.
