In an OSPF hub-and-spoke topology, what needs to be done, if anything, to ensure that the spoke routers would never be selected as DR and BDR?

In an OSPF hub-and-spoke topology, what needs to be done, if anything, 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).

Explanation: Technologies such as Frame Relay or DMVPN that use a hub-and-spoke topology need to have the DR as the hub router. Use the ip ospf priority command on the specific interface that is used to connect to the other sites and set the priority value to 255.
