Static routes are manually configured by a network administrator, while dynamic routes are automatically learned and adjusted by a routing protocol. 02.

Path selection Static routing uses a single preconfigured route to send traffic to its destination, while dynamic routing provides multiple available routes to the destination. 2. Ability to update routes Network administrators must manually reconfigure static routes in order to adjust routes. Dynamic routing uses algorithms to automatically update with the preferred route change. 3. Routing tables Static routing has a smaller routing table with only one entry for each destination, while dynamic routing requires routers to send out their entire routing tables to identify route availability. 4. Use of protocols and algorithms Static routing doesn't use protocols or complex routing algorithms. Dynamic routing uses distance vector protocols, such as RIP and IGRP, and link state protocols, such as OSPF and IS-IS, to adjust routes. 5. Computation and bandwidth requirements Static routing requires less compute power and bandwidth, as it only has one preconfigured route. Dynamic routing requires more computation and bandwidth to generate multiple route possibilities. 6. Security 1|Page GEETHARANDA MCR CT/2017/019 Static routing is more secure because it doesn't share routes across the entire network. Dynamic routing creates more security risks because it shares complete routing tables across the network. 7. Use cases Static routing is best used in smaller networks with fewer routers and is ideal for networks with unchanging network architecture. Dynamic routing is well suited for larger, more complex networks that have multiple routers, and its flexibility makes it ideal for network architectures that frequently change. 05.

In a fully specified static route, both the output interface and the next hop are specified. This form of static route is used when the output interface is a multiaccess one and it is necessary to explicitly identify the next hop. The next hop must be directly attached to the specified output interface. A fully specified route is valid when the specified IPv6 interface is IPv6-enabled and up. 08. 1. Network ID 2.
