Based on the Linux operating system-how to build a router-Linux Enterprise Application-Linux server application information, the following is a detailed description. Network structure. The computer of the Linux router is identified as A. It is connected to three network segments, 192.168.1.0/24, 10.0.0.0/8, and 172.16.0.0/16.
(400) {this. resized = true; this. width = 400; this. alt = 'click here to open new window';} "onmouseover =" if (this. resized) this. style. cursor = 'hand'; "onclick =" window. open ('HTTP: // edu.cnzz.cn/newsfile/051024073345440.png'); ">
Computer A must have three NICs connected to the three network segments.
Hypothesis:
Eth0 is connected to 172.16.0.0,
Eth1 is connected to 10.0.0.0,
Eth2 is connected to 192.168.1.0.
Configure eth0 first. Assign the address 172.16.1.1 to this network interface and run the following command:
