Open the PT Activity. Perform the tasks in the activity instructions and then answer the question. A network administrator is configuring multiarea OSPFv3 on the routers. The routing design requires that the router RT1 is a DROTHER for the network in Area 0 and the DR for the network in Area 1. Check the settings and status of the routers. What can the administrator do to ensure that RT1 will meet the design requirement after all routers restart?

Check the settings and status of the routers. What can the administrator do to ensure that RT1 will meet the design requirement after all routers restart?

• Use the ipv6 ospf priority 0 command on the interface g0/0 of RT1.
• Use the ipv6 ospf priority 10 command on the interface g0/2 of RT1.
• Configure the loopback 0 interface with 6.6.6.6.
• Restart all routers except for RT1.
• Change the router ID to 5.5.5.5 on RT1.

Explanation: In a multiarea OSPF network, if the interface priority is the same for all routers, then the router with highest router ID becomes the DR and the router with second highest router ID becomes BDR. Changing the router ID can influence the DR/BDR election. However, for an ABR, the same router ID will be used for DR/BDR elections for multiple areas. In this case, it is better to use the interface priority value to manage the DR/BDR election for different areas, because this value is interface specific.
