In an OSPF hub-and-spoke topology, what needs to be done to ensure that the spoke routers would never be selected as DR and BDR? Because nonbroadcast networks do not elect a DR/BDR, nothing needs to be done. All routers must be configured with an OSPF interface priority of 0 (ip ospf priority) to disable the DR/BDR election process. All spoke routers need to be configured with an OSPF interface priority of 0 (ip ospf priority) so that they will not become the DR/BDR. | 111 111 CISCO Close Window Assessment System 1.

I It reduces OSPF information exchange overhead. _l It encrypts routing tables to prevent unauthorized viewing. S It prevents routing information from being falsified in transit. S It ensures that routing information comes from a valid source router. I It ensures that OSPF routing .
