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.

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.
