Answer» The LSAS (Link-State ADVERTISEMENTS) are used by OSPF routers to exchange routing and topology information. When two neighbors decide to exchange routes, they send each other a list of all LSA in their respective topology database. Each router then checks its topology database and sends Link State REQUEST (LSR) message requesting all LSAs that was not FOUND in its topology table. Other router responds with the Link State Update (LSU) that CONTAINS all LSAs requested by the neighbor.
