Abstract
Techniques for synchronizing routing data include determining whether conditions are satisfied for one-way transfer with an adjacent router. If it is determined that conditions are satisfied for one-way transfer of routing table data with the adjacent router, then a refresh-notice message is sent from the initiating router to the adjacent router. The refresh-notice message includes data that indicates a particular direction for transfer of routing table data. If the particular direction is inbound, then a copy of an adjacent routing table is received without sending a copy of the initiating router's own routing table. If the particular direction is outbound, then a copy of the own routing table is sent without receiving a copy of the adjacent routing table.
