Of the four routing protocols below, which one uses Bellman-Ford algorithm for its route selection?
IS-IS
RIP
EIGRP
OSPF
Routing Information Protocol uses Bellman-Ford Algorithm (distance-vector) to determine the best route to use to reach a destination network. The distance is measured in hops and the vector is the direction to which a datagram is sent over a given set of network nodes. EIGRP uses Diffusing Update Algorithm (Advanced Distance-Vector Routing Protocol), and both IS-IS and OSPF use Dijkstra's Algorithm (Link-State Routing Protocol).
