Refer to the graphic. R1 is unable to establish an OSPF neighbor relationship with R3. What are possible reasons for this problem? (Choose two.)

The correct answer is D. The hello and dead interval timers are not set to the same values on R1 and R3. F. R1 and R3 are configured in different areas.. This question is to examine the conditions for OSPF to create neighborhood. So as to make the two routers become neighbors, each router must be matched with the following items: 1. The area ID and its types; 2. Hello and failure time interval timer; 3. OSPF Password (Optional);

CA static route has been configured from R1 to R3 and prevents the neighbor adjacency from
DThe hello and dead interval timers are not set to the same values on R1 and R3.
EEIGRP is also configured on these routers with a lower administrative distance.
