Static Routes

A static route is routing information manually configured by a user or network administrator. When the topology of the network or the status of the link changes, the network administrator needs to manually modify the related static routing information in the routing table.

Static routing information is private by default and will not be passed to other routers. Of course, the network administrator can also make the router share by setting it. Static routes are generally applicable to a relatively simple network environment. In such an environment, the network administrator can easily understand the topology of the network and set up correct routing information.

Generally used in the scenario where the internal network has a three-layer switch. Or the secondary route uses the routing mode, or in the scenario of using the VPN.
