Dynamic routing protocols help the network administrator manage the time-consuming and exacting process of configuring and maintaining static routes.
Dynamic routing automatically adapts topology to reroute traffic if possible.
Dynamic routing is generally independent of the network size.
Dynamic routing protocols are used to dynamically calculate and update routing tables in a network, as opposed to static routing, where routing tables are manually configured. Here are three advantages of dynamic routing protocols over static routing protocols:
Lower administrative overhead: Dynamic routing protocols reduce the amount of manual work required to maintain routing tables, compared to static routing. With dynamic routing protocols, routers exchange information about the network topology and automatically update their routing tables. In contrast, with static routing, administrators must manually configure each router's routing table, which can be time-consuming and prone to human error.
Increased network availability: Dynamic routing protocols allow routers to automatically reroute traffic around network failures, which improves network availability. When a link or router fails, the dynamic routing protocol detects the failure and recalculates the best path to the destination. In contrast, with static routing, if a link or router fails, traffic will continue to be routed to the failed destination, resulting in network downtime.
Greater network scalability: Dynamic routing protocols can handle changes in network topology and traffic patterns much more efficiently than static routing. As the network grows and changes, the routing protocol will automatically adapt to the new topology and traffic patterns, without requiring manual updates to routing tables. This makes dynamic routing protocols much more scalable than static routing.
Option D and E, "easier to implement qualified next hops" and "easier ECMP route implementation", are not advantages of dynamic routing protocols over static routing protocols in general. They may be specific advantages of certain dynamic routing protocols over certain static routing protocols, but they are not universal advantages of dynamic routing protocols over all static routing protocols.
