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.
- One of the spoke routers will need to be configured as the DR by setting the OSPF interface priority higher than 1 (ip ospf priority).
