In a communications network comprising a plurality of routers the routers exchange router control information by transmitting and receiving control messages. A method is disclosed for transmitting, receiving, acknowledging, and verifying receipt of the message or messages between at least two routers. A transmitting router maintains a list of unacknowledged messages and periodically retransmits all unacknowledged or incompletely acknowledged messages. A receiving router insures that a received message is not a duplicate and is not out of sequence before transmitting an acknowledgement message. The disclosed method may be compatible with other router control message protocols, providing interoperability.
