Which characteristics are representative of a link-state routing protocol? (Choose three.)
A.
provides common view of entire topology
B.
exchanges routing tables with neighbors
C.
calculates shortest path
D.
utilizes event-triggered updates
E.
utilizes frequent periodic updates
Link-state routing protocols, such as OSPF and IS-IS, create a topology of the network and place themselves at the root of the tree. Link-state protocols implement an algorithm called the shortest path first (SPF, also known as Dijkstra’s Algorithm) to determine the path to a remote destination.
