OSPF is configured over a Frame Relay network as shown in the exhibit. All PVCs are active.However, R1 and R3 fail to see all OSPF routes in their routing tables. The show ip ospf neighbor command executed on R2 shows the state of t he neighbors. What should be done to fix the problem? （）
A. The ip ospf network broadcast command should be configured on each Frame Relay interface
B. The ip ospf network non -broadcast command should be configured on each Frame Relay interface
C. Th e ip ospf priority value on the spoke routers should be set to 0
D. The ip ospf priority value on the hub router should be set to 0
E. The neighbor command should be configured under the OSPF routing process on all routers

You have implemented mutua l route redistribution between OSPF and EIGRP on a border router. When checking the routing table on one of the EIGRP routers within the EIGRP routing domain, you are seeing some, but not all of the expected routes.What should you verify to troubleshoot this problem?（）
A. The border router is using a proper seed metric for OSPF
B. The border router is using a proper seed metric for EIGRP
C. The administrative distance is set for OSPF and EIGRP
D. The missing OSPF routes are present in the routing table of the border router
E. The subnet keyword on the border router in the redistribute OSPF command

You have completed an OSPF implementation, and you are verifying OSPF operation. During this verification, you notice that the OSPF route of 172.16.10.0 is repeatedly appearing and disappearing from the routing table. Further investigation finds that the OSPF CPU utilization is very high and the routers are constantly performing SPF calculations. You determine that 172.16.20.2 is the source of the 172.16.10.0 route. Using the show ip ospf database router 172.16.20.1 command, you notice that when this show command is performed repeatedly, the contents of the LSA change every few seconds.What could be the cause of this problem?（）
A. OSPF authentication errors between some of the routers
B. Two routers have the same OSPF router ID
C. Issues with mistuned OSPF timers
D. OSPF LSA pacing issues between some of the routers
E. OSPF neighbor adjacency problems between some of the routers

A. ip ospf authentication null
B. ip ospf authentication message - digest
C. ip ospf authentication -key whatever- it - is
D. ip ospf message - digest - key 1 md5 whatever - it - is
E. ip ospf md5 1 key whatever - it - is
