What protocol requires all routers in the same domain to maintain a map of the network?
OSPF (Open Shortest Path First) is a link-state routing protocol. In OSPF, all routers in the same area maintain an identical database describing the network's topology. This map allows each router to independently calculate the shortest path tree using the Dijkstra algorithm. Each router sends link-state advertisements to all other routers, providing a complete and updated view of the network.
D. The protocol that requires all routers in the same domain to maintain a map of the network is the "Link State Routing Protocol." In a link state routing protocol, each router in the network maintains a detailed map of the network's topology. This map includes information about all the routers in the network, the links between them, and various metrics or costs associated with those links. The most common example of a link state routing protocol is the Open Shortest Path First (OSPF) protocol.
