Question

Quizplus · Accepted Answer

In OSPF, a link is defined as a connection between two neighboring routers. Each interface on a router is considered a link, and the state of each link is advertised through the LSAs (Link-State Advertisements) sent by the router. Therefore, a router's interface is referred to as a link in OSPF. Choice A (link-state) refers to the overall OSPF protocol mechanism that uses link-state information to build a complete network topology. Choice B (cost) is a metric used in OSPF to determine the best path to a destination, based on the total cost of each link involved in the path. Choice D (area) refers to a grouping of routers and links in OSPF, based on administrative and technical boundaries, which helps to reduce the size and complexity of the routing domain.
