Advantage of Dynamic Routing

C

Dynamic routing is a network routing technique in which the routing tables are automatically updated based on the current state of the network. Dynamic routing protocols enable routers to share information about the network topology with each other, allowing them to select the best path for forwarding packets to their destination.

The advantages of dynamic routing over static routing are:

C. Dynamic routing can provide increased network availability when compared to static routing. Dynamic routing protocols such as OSPF (Open Shortest Path First), BGP (Border Gateway Protocol), and EIGRP (Enhanced Interior Gateway Routing Protocol) are designed to automatically detect network changes and adjust the routing tables accordingly. This means that if a link or a router fails, the routing protocol can quickly find an alternate path to the destination, ensuring that the network remains available.

A. Unlike static routing, dynamic routing provides redundant IP addresses for end-user devices. Dynamic routing protocols can distribute IP addresses to end-user devices, which means that if one router fails, another router can take over and continue to provide IP connectivity. This redundancy can improve network availability and reduce downtime.

B. Unlike static routing, dynamic routing requires no initial user configuration. Dynamic routing protocols automatically discover the network topology and dynamically adjust the routing tables. This means that network administrators do not need to manually configure every router on the network, saving time and reducing the risk of configuration errors.

D. Dynamic routing provides DNS services along with IP connectivity; static routing does not. This statement is incorrect. Dynamic routing protocols do not provide DNS services, and neither does static routing. DNS (Domain Name System) is a separate protocol that maps domain names to IP addresses.

In summary, dynamic routing provides advantages over static routing in terms of network availability, redundancy, and ease of configuration. It is an important technique for building large-scale networks that require automatic adaptation to changing network conditions.
