OSPF standard, however, does not allow routers to do so without actually changing the topology view of the network. Asynchronous flooding algorithm ensures routers' LSDBs stay in sync in the presence of topology changes. This effectively causes the adjacencies to be removed from the router-LSAs, which may not be acceptable in some cases.
