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.

共用题干Energy CycleDo you find getting up in the morning so difficult that it's painful?This might be called laziness, but Dr. Kleitman has a new explanation.He has proved that everyone has a daily energy cycle.During the hours when you labor through your work you may say that you are"hot".That's true.The time of day when you feel most energetic is when your cycle of body temperature is at this peak.For some people the peak comes during the morning. For others it comes in the afternoon or evening. No one has discovered why this is so,but it leads to such familiar words as:"Get up, John!You'll be late for work again!"The possible explanation to the trouble is he is at his tempera-ture-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.You can't change your energy cycle,but you can learn to make your life fit it better. Habit can help,Dr. Kleitman believes.Maybe you're sleepy in the evening but feel you must stay up late anyway.Counteract your cycle to some extent by habitually staying up later than you want to.If your energy is low in the morning but you have an important job to do early in the day,rise before your usual hour. This won't change your cycle,but you'll get up steam and work better at your low point.Get off to a slow start,which saves your energy.Get up with a leisurely yawn and stretch.Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before.Whenever possible,do routine work in the afternoon and save tasks requiring more energy for your sharper hours.If your energy peak is in the evening,you might like to get up late.A:Right B:Wrong C:Not mentioned
