The correct answer is D. Change R1 and R2 to a network type of point-to-point. The OSPF adjacency is stuck in the EXSTART/DR state because the broadcast network type is being used by default on the /31 link. On a /31 point-to-point link, OSPF neighbors should not attempt DR/BDR election. Changing the OSPF network type to point-to-point on either R1 or R2…
Question
Refer to the exhibits. An engineer has applied the above configuration to R1 and R2, however, the router’s OSPF adjacency never progresses past the “EXSTART/DR” state. Which configuration action on either router will allow R1 and R2 to progress past the “EXTART/DR” state?
Exhibits
Options
- AChange the IP address and mask applied to interface 1/1/1 to a valid mask supported by RFC
- BEnsure the OSPF process is not configured with passive-interface default.
- CRemove the L3 MTU configuration.
- DChange R1 and R2 to a network type of point-to-point.

Explanation
The OSPF adjacency is stuck in the EXSTART/DR state because the broadcast network type is being used by default on the /31 link. On a /31 point-to-point link, OSPF neighbors should not attempt DR/BDR election. Changing the OSPF network type to point-to-point on either R1 or R2 ensures correct adjacency formation and allows the routers to progress to the FULL state.
