* Dynamic Routing Protocols Overview:
* Dynamic routing protocols enable routers to exchange routing information dynamically, allowing them to adapt to changes in the network topology automatically.
* Explanation of Each Protocol:
* OSPF (Open Shortest Path First):A link-state routing protocol that uses the Dijkstra algorithm to calculate the shortest path to destinations. It is widely used in enterprise networks.
* IS-IS (Intermediate System to Intermediate System):Another link-state routing protocol, similar to OSPF, but primarily used in service provider networks.
* RIP (Routing Information Protocol):A distance-vector routing protocol that uses hop count as its metric. It is simple but less scalable compared to OSPF and IS-IS.
* BGP (Border Gateway Protocol):A path-vector routing protocol used for inter-domain routing (e.
g., between autonomous systems). It is the backbone of the Internet.
* Conclusion:All four options (OSPF, IS-IS, RIP, and BGP) are dynamic routing protocols.
