Refer to the exhibit. Two routers are connected by Frame Relay and are running OSPF bet ween them. 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
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 routersB. Two routers have the same OSPF router IDC. Issues with mistuned OSPF timersD. OSPF LSA pacing issues between some of the routersE. OSPF neighbor adjacency problems between some of the routers
Refer to the exhibit. You have completed an OSPF implementation, and you are verifying OSPF operation. You notice that router A and router B are stuck in the two - way state. From the show ip ospf interface command output, what is the cause of this issue?（）A. All OSPF implementations must have at le ast one interface in area 0.B. You are attempting to run in the broadcast mode over an NBMA interface.C. Both routers are configured to function as a BDR; therefore, there is no DR router.D. Someone has changed the OSPF router ID; therefore you must clear the OSPF process.E. The OSPF priority is set to 0 on both routers; therefore neither can become the DR.
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.
Refer to the exhibit. Which statement is true about the configuration? () A. RTA will not establish an OSPF adjacency w ith RTBB. RTA will send OSPF hello packets, but will not send OSPF updatesC. RTA will not accept OSPF hello packets from RTBD. RTA will send OSPF updates, but will not establish an adjacency with RTB
When a router undergoes the exchange protocol within OSPF, in what order does it pass through each state?() A.exstart stateexchange stateloading statefull stateB.exstart statefull stateloading stateexchange stateC.Loading stateexchange statefull stateexstart stateD.exstart stateloading stateexchange statefull state
Refer to the exhibit. When running OSPF, What would cause router A not to form an adjacency with router B?() A.The loopback addresses are on different subnetsB.The value of the dead timers on the router are differentC.Route summarization is enabled on both routersD.The process indentifier on router A is different than the process identifier on router B
Which of the following data structures exist on a router for the OSPF routing protocol？（）A、OSPF topology tableB、OSPF interface tableC、OSPF routing information baseD、OSPF link-state databaseE、OSPF adjacency tableF、OSPF neighbor table
Which of the following must match for two directly connected routers running OSPF to establish a neighbor adjacency?（）A、area IDsB、process IDsC、router IDsD、hello timers
What does the OSPF command capability vrf-lite achieve？（）A、It enables provider edge （PE） specific checks on a router when the OSPF process is associated with the VRFB、It disables provider edge （PE） specific checks on a router when the OSPF process is associated with the VRFC、It enables the exchange of the "VRF-Lite" capability when the OSPF adjacency is formed.D、It disables the MPLS processing on the OSPF learned routes inside the VRF

During OSPF adjacency formation, in what state is a router when it is negotiating to be in charge of the database synchronization process?（）A、InitB、2WayC、ExStartD、Exchange
This question is about the formation of OSPF adjacency. An OSPF adjacency will not form correctly across a point-to-point link in the same area. Which would most likely cause this problem？（）A、Each interface has a different OSPF cost.B、Each interface is configured with secondary addresses as well as primary addresses.C、Each interface has a different MTU size.D、Each interface is configured with theip unnumbered loopback 0 command.
You have just completed an OSPF implementation. While executing your verification plan, you determine that R1 is not able to establish full OSPF adjacency with R2. The show ip ospf neighbor comman d output on R1 shows that R2 is stuck in the INIT state. What could be the cause of this problem?（）A、DR and BDR election errors between R1 and R2.B、The R2 router has not received the OSPF hello packets from the R1 router.C、Mismatched interface ma ximum transmission unit (MTU) configuration between the R1 and R2.D、Mismatched OSPF hello interval configuration between the R1 and R2E、Corrupted LSAs exchanges between the R1 and R2.
