Abstract
This application discloses a link-state advertisement LSA sending method, an apparatus, and a system, to reduce a quantity of LSA sending times. The method includes: generating, by a first router, a first path table based on level location information of the first router, level location information of a second router, and level location information of at least one third router; sending, by the first router, a first link state update LSU message to the second router; receiving, by the second router, the first link state update LSU message from the first router; updating, by the second router, a link state database LSDB of the second router based on a first LSA; and sending, by the second router, the first LSA to a router corresponding to an identifier in the first path table.
