Depending on the type of algorithms used, routing protocols are classified into distance-vector protocols and link-state protocols. Which of the following routing protocols are link-state protocols?
Comprehensive and Detailed Step-by-Step Explanation:
Distance-Vector Protocols:
Distance-vector protocols determine the best path based on the distance to a destination and periodically share the entire routing table with neighbors.
Example: RIP is a distance-vector protocol.
Link-State Protocols:
Link-state protocols share information about directly connected links, enabling routers to build a complete map of the network.
OSPF (Open Shortest Path First) and IS-IS (Intermediate System to Intermediate System) are link-state protocols that use Dijkstra’s algorithm to calculate the shortest path.
Border Gateway Protocol (BGP):
BGP is neither a distance-vector nor a link-state protocol. Instead, it is classified as a path-vector protocol that selects the best path based on attributes such as AS-path, next-hop, and local preference.
