What are static routing and dynamic routing? What are their respective characteristics? STATIC routing is a fixed route manually configured by the Administrator in the router. The route explicitly specifies the path required for the packet to arrive at the destination, the static route does not change unless the network administrator intervene. Static Routing cannot respond to changes in the network. Therefore, Static Routing is generally used in a network with a small network size and a relatively fixed topology. Static Routing features 1. It allows precise control of routing behavior; 2. reduces network traffic; 3. It is unidirectional; www.2cto.com 4. simple configuration. Dynamic routing is a process in which routers in the network communicate with each other, transmit route information, and update the router table using the received route information. It is implemented based on a certain routing protocol. Common routing protocols include distance vector routing protocol (such as RIP) and link status routing protocol (such as OSPF ). The routing protocol defines some rules for a router to communicate with other routers. Dynamic Routing protocols generally have routing algorithms. Required steps for the routing algorithm: 1. Transmit route information to other routers; 2. Receive route information from other routers; 3. Calculate the optimal route for each target network based on the received route information and generate a route selection table. 4. Make a timely response based on the changes in the network topology, adjust the route to generate a new route selection table, and notify other routers of the topology changes in the form of route information. Dynamic Routing is suitable for networks with large network sizes and complex topologies. Dynamic Routing features: 1. Manual maintenance is not required, reducing the workload of administrators. 2. Occupied network bandwidth. 3. Run the routing protocol on the vro so that the vro can automatically adjust route entries based on the changes in the network topology;
