Because it is a number of network segments, there will be multiple routing servers, then we build one of these route servers in a local area network, and we take four routing servers as an example, they are in a local area network. The IP of the NIC is: 192.168.0.1; 192.168.0.2; 192.168.0.3; 192.168.0.4, according to the WINDOWS soft routing method, the gateway 192.168.0.1 is assigned to 192.168.0.2; IP is 192.168. The gateway of 0.2 is assigned to 192.168.0.3; IP is equipped with 192.168.0.3 to 192.168.0.4; IP is equipped with a gateway 192.168.0.4 into 192.168.0.1. That is, the gateway of their network card is set to cycle.
