第4题：

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 network planning diagram shows a large internetwork with many routers. The configurations show that OSPF has been enabled on all interfaces, I P addresses correctly configured, and OSPF workinG. For which of the following cases would you expect a router to create and flood a Type 2 LSA?（）

• A、When OSPF is enabled on a LAN interface, and the router is the only router connected to the subnet.
• B、  When OSPF is enabled on a point - to -point serial link, and that router has both the higher router ID and higher interface IP address on the link.
• C、When OSPF is enabled on a Frame Relay point - to - point subinterface, has the lower RID and lower subinterfa ce IP address, and otherwise uses default OSPF configuration on the interface.
• D、When OSPF is enabled on a working LAN interface on a router, and the router has been elected BDR.
• E、None of the other answers is correct.
