Question:
Which step in the link-state routing process is described by a router flooding link-state and cost information about each directly connected link?
- building the topology table
- selecting the router ID
- exchanging link-state advertisements
- injecting the default route
Explanation: According to the link-state routing process, once neighbor adjacencies are established, routers begin exchanging link-state advertisements (LSAs). During this step, each router floods information regarding the state and cost of its directly connected links to its neighbors. These neighbors then immediately forward the information to their own neighbors until all routers in the OSPF area possess identical link-state information.
