The public network address of the ipv4 applied by the R1 router is 202.101.12.1 ; the public network address of the R3 application is 202.101.23.3. Different prefixes (network number + mask, indispensable), belonging to different routes in the routing table Configuration command Ip default-network !! Note that this order must be matched because 16 bits The vocation of the router is to maintain the routing table and use the routing table for data forwarding. The routing table contains routing entries or routing entries learned through various channels. The simplest and most straightforward method is to use static manual configuration to create routing entries for the router. This method is the most direct and controllable. The highest, the most simple configuration. In a small network, there seems to be no problem with static routing on the whole network. However, in a large network, if you use static routes purely, the workload is very large, not only the workload is large, but another more important defect is Static routes cannot be adjusted according to changes in network topology. Therefore, in large-scale networks,cisco ccna training, we often use static + dynamic routing protocols to complete route deployment.
