experimental diagram Analysis: Static routing is the choice of the specified route, in this figure with the routing function of the server has3Card ,eth0Connect to the intranet,eth1connect the CTT,eth2connect to telecommunications. However, there can only be one network card as a gateway in this network. Use that NIC as a gateway? You can think about it. Yes, it is.eth1oreth2, if you selecteth1soeth2will act as a backup network, if it iseth2, theneth1will be a backup. But you can't set the intranet .eth0as a gateway, it does not know how to send data to the next route, so that data is cycled through the server and cannot be sent.

Static routing application: Use eth1 as the primary network connection,eth2 as the backup network. We can open a port on the server and use a static route to assign it to the eth2 card. Allow a small number of people to access eth2 traffic.

Note: This is an application that is used as a static route.
