Flooding Procedure Each DR forwards a new LSA the first time it is received, regardless of which neighbor it was received from (source independent flooding). If the router has multiple interfaces, then the new LSA is forwarded only on interfaces associated with Dependent Neighbors that are not covered by the neighbor from which the LSA was received. Each BDR forwards a new LSA after a small delay, if the neighbors from which the LSA has been received do not cover all Backup Dependent Neighbors. If the router has multiple interfaces, then the new LSA is forwarded only on interfaces associated with Backup Dependent Neighbors that are not covered by neighbors from which the LSA was received. Source-dependent flooding is allowed as an option, to provide flooding along min-hop paths if desired. Note that the flooding procedure is described without mentioning adjacencies. This allows it to be used in other MANET applications. |
