When learning a new route, if a LSA received is not found in the topological database, what will an internal OSPF router do?()
A. The sequence numbers are checked, and if the LSA is val id it is entered into the topology database.
B. The LSA is placed in the topological database and an acknowledgement is sent to the transmitting router.
C. The LSA is dropped and a message is sent to the transmitting router.
D. The LSA is flooded imme diately out of all the OSPF interfaces, except the interface from which the LSA was received.

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

What does the command clear ipv6 ospf process accomplish?()
