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.

You have a router running BGP for the MPLS network and OSPF for the local LAN network at the sales office. A route is being learned from the MPLS network that also exists on the OSPF local network. It is important that the router chooses the local LAN route being learned from the downstream switch running OSPF rather than the upstream BGP neighbor. Also， if the local OSPF route goes away， the BGP route needs to be used. What should be configured to make sure that the router will choose the LAN network as the preferred path？（）A、static route needs to be addedB、floating static route needs to be addedC、bgp backdoor commandD、ospf backdoor command
