• ISIS is a link–state routing protocol designed for use in an environment where intermediate systems may not be capable of running IP. It was developed as an alternative to the Open Shortest Path First (OSPF) protocol.
• OSPF (Open Shortest Path First) is a link–state routing protocol that is used extensively in IP networks. It is characterized by its fast convergence and shortest path first algorithm. OSPF uses a hierarchical structure, allowing it to scale well, even with large networks. OSPF operates on all popular Internet Protocol (IP) networks, including IPv4, IPv6, and IPX
Isis and Ospf are both link-state routing protocols used in computer networks.
Isis (Intermediate System to Intermediate System) is a routing protocol designed for large networks, such as those found in telco and enterprise networks. It is a distance-vector protocol that uses a hierarchical structure for routing and utilizes a multi-level flooding algorithm for finding the best paths through a network.
Ospf (Open Shortest Path First) is a link-state routing protocol designed for use in smaller networks, such as those found in local area networks. It is a link-state protocol that uses a shortest-path algorithm to determine the best paths through a network. Unlike Isis, Ospf uses a single-level flooding algorithm.
