Each router has been configured with the appropriate network statements under router ospf 1, but the routers are not forming an adjacency. Which of the following three commands could be configured on each router to correct this problem?（）A. RouterC(config - if)#ip ospf network broadcast RouterD(config - if)#ip ospf network broadcastB. RouterC(config - if)#ip ospf network point - to - point RouterD(config - if)#ip ospf network point - to - pointC. RouterC(config - router)#neighbor 10.100. 100.4 RouterD(config - router)#neighbor 10.100.100.3D. RouterC(config - router)#neighbor 10.255.255.254 RouterD(config - router)#neighbor 10.255.255.253
Refer to the exhibit. OSPF is configured on all routers in the network. On the basis of the show ip ospf n eighbor output, what prevents R1 from establishing a full adjacency with R2? () A. Router R1 will only establish full adjacency with the DR and BDR on broadcast multi- access networks.B. Router R2 has been elected as a DR for the broadcast multiaccess network in OSPF area 1.C. Routers R1 and R2 are configured as stub routers for OSPF area 1 and OSPF area 2.D. Router R1 and R2 are configured for a virtual link between OSPF area 1 and OSPF area 2.E. The Hello parameters on routers R1 and R2 do not m atch.

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 interfaceB. The ip ospf network non -broadcast command should be configured on each Frame Relay interfaceC. Th e ip ospf priority value on the spoke routers should be set to 0D. The ip ospf priority value on the hub router should be set to 0E. The neighbor command should be configured under the OSPF routing process on all routers
