According to the present invention, methods and apparatus are provided to improve the link state routing protocol (LSRP) to prevent transient loops during topology changes. Broadcast and shared multicast traffic may be dropped on particular ports upon detecting link state change until neighboring nodes have computed routes using updated link state information. An acknowledgment is sent upon receiving a link state record. Sync and sync-ack packets are used to determine when link state information is synchronized with that of peer nodes.
