How do I connect three CIDR blocks using two routes?

Q: There are three CIDR blocks, each of which contains two computers. The IP address segment in CIDR Block A is 10.0.0.2 ~ 10.0.0.2. The IP address segment in CIDR Block B is 192.168.0.2 ~ 192.168.0.3, the IP address segment in CIDR Block C is 172.160.2 ~ 172.160.3. Now we need to connect the three CIDR blocks to form a LAN. What should I do?

A: In small and medium-sized LAN networks, you can use two routers to connect the three CIDR blocks. You only need to tell "router A" the address of "CIDR Block C" and "router B" the address of "CIDR Block ", in this way, the two routers can expand their effective management scope.

To set static routing, open Routing and Remote Access in the control panel of the Windows 2000 Server System that acts as "router, select "IP Route Selection"> "static route" on the local computer, right-click and choose "static route ..." Add static routes. Select "Local Connection" in the dialog box, enter the network number of "CIDR Block C" in "target". Note that the last IP address is 0, and the subnet mask is 255.255.255.0, the gateway address is the IP address of "router C" connected to "CIDR Block C", that is, 172.160.1.

Next, set "target" in the related project of "vrob B" to the network number of "CIDR Block A", that is, the last digit of 10.0.0.0 is also 0 ), the gateway IP address is 10.0.0.1, And the subnet mask is 255.255.255.0. Note that such a connection scheme is not suitable for large networks.
