QuestionQ15

OSPF

Which two events cause a router to advertise a directly connected network to its OSPF neighbors?

Choose two
  • A When an OSPF adjacency is established.
  • B When an interface has the OSPF passive option enabled.
  • C When a static route to the 224.0.0.6 address is created.
  • D When a static route to the 224.0.0.5 address is created.
Explanation

OSPF advertises an OSPF-enabled interface’s connected network through its link-state information. Once an OSPF adjacency is established, the router exchanges that information with the neighbor. A passive OSPF interface stops sending Hellos and forming adjacencies on that interface, but its connected network continues to be advertised. Static routes to the OSPF multicast addresses do not cause connected-network advertisements.
