Dynamic Route configuration and working principle

Dynamic routing configuration and working principle dynamic routing: vrouters in the network communicate with each other and transmit route information. The process of updating and maintaining the route table based on the characteristics of a specific routing protocol is as follows: reduce management tasks, but use network bandwidth dynamic routing protocol: -- transmit route information to other routers -- receive route information from other routers -- calculate the optimal route to each target network based on the received route information, and then generate a route table-adjust the route table in time according to the network extension changes, while remembering the working principle of his router declaring extension and modification of information routing protocol RIP: 1. First, the router learns to the direct connection CIDR block. 2. When the update cycle of the router reaches 30 s, the router will send the route information to the neighbor. 3. After 30 s, the second update cycle of the router will arrive, note: The measured value (Metric) of RIP takes the number of hops as the unique measurement value.
