Discard hard routing! Detailed tutorial on creating a soft route (figure)

When talking about routing, some new friends may not understand what a "soft" route is. Here I will briefly introduce the differences between soft routing and hard routing. What we usually encounter in our daily lives is "hard" routing. Hardware routing is a dedicated hardware device, including a processor, power supply, and embedded software. It provides a set router function.

Soft routing is a routing solution formed by combining a desktop or server with software. It mainly relies on software settings to achieve the router function.

There are many advantages of soft routing, such as the use of cheap desktops, with free Linux software, flexible routing, and powerful desktop processor performance, so the processing efficiency is good, it is easy to expand. However, technical personnel are also required to have more professional knowledge, such as setting methods and parameter design, and the setting is also complicated, and technical personnel must be able to adapt to specific technical capabilities. At the same time, if the hardware configuration of the desktop is poor or unreasonable, and the function of the router works for a long time, the chance of failure will be very high. The cost of building a desktop is not low, but if you want to use a server, the cost is higher, and the learning process of technicians is also cumbersome.

The practice of hard routing is to configure a dedicated machine. Like a PC, Hard Routers include power supplies, internal BUS, primary storage, flash memory, processors, and operating systems. They are designed for routing functions with low costs. The software in the router is deeply embedded into the hardware, including the optimization of various device drivers, different system cpu optimization policies, etc. This software is not an application software, but a system software, and hardware cannot be separated.

Because the architecture design takes into account the long-term operation, the stability is ensured. In addition, most of the important functions have been completed in the built-in system design, so there is little effort to set manual management, it can save time for technical or network administrators. However, if a certain hardware specification is not powerful and the scalability is not wide, it may fail to meet the requirements. In particular, if the vendor does not provide the feature, therefore, technical or network administrators cannot solve the problem.

Due to computer restrictions, the soft route can only use the ethernet card. Therefore, it is basically limited to the connections between Ethernet networks. The soft route connection is used only when multiple network segments are divided between Ethernet networks. When users do not have high requirements on network and data transmission or only implement NAT translation, after all, for schools and Internet cafes, the price of desktops can save a lot of cost compared to the professional hard routing of tens of thousands of yuan.

The following describes how to use a simple method to implement the soft routing function. First, install Windows 2000 Server, and enable "Start/Program/management tool/route and remote access to RRAS) 1 ),

Figure 1

Open the "Routing and Remote Access" window, right-click the local server name, and select "configure and enable Routing and Remote Access" option 2 in the menu ),

Figure 2

Open the "route and Remote Access Server Installation Wizard" window, select "network router" in the following, and click Next to continue. 3.

The "TCP/IP" protocol is displayed in the "protocol" list. Because the TCP/IP protocol supports the routing function, select "yes, all available protocols are on the list. Click "no" in the last window that appears, and do not use dial-up requests to access the remote network. Then, click "Next. Then click to complete the "route and Remote Access Server Installation Wizard ". Next, set the route, right-click the local server, and select "properties" in the pop-up menu. The window shown in 4 appears, under the "General" column, select "for LAN only) routing" and click "OK.

Figure 4

Under the "Tree" directory, select local server/IP route/General, right-click and select "New Route Selection protocol", as shown in Figure 5.

Figure 5

When "new route select protocol" is displayed, select "RIP version 2 for Internet Protocol" and click OK. 6. Among them, RIP2 applies to small and medium networks, and OSPF applies to large networks. Therefore, RIP2 is selected here. Note: either of the two network protocols can be selected and cannot be used at the same time)

Figure 6

In "IP Route Selection", right-click "RIP" and select "New Interface", as shown in 7.

Figure 7

Click "new interface for RIP version 2 of Internet protocol", select "Local Connection", and click OK. 8. Similarly, add another interface "local connection 3 ". The result 9 is displayed.

After configuring the host as a soft route, you must set up a gateway on the host of the client. In turn, open "Start/control panel/network and Internet connection/network connection ", right-click "properties" of "Local Connection", and the "10" page appears. Select "Internet protocol TCP/IP" and click Properties, as shown in Figure 11. If the client is in the 192.168.1.0 CIDR Block and 192.168.1.1 is set in the "Default Gateway" column, if the client is in another CIDR block, for example, in the 192.168.10.0 CIDR block, set 192.168.10.1 in the "Default Gateway" column. After completing the settings, click OK to restart the computer.

In addition to using RRAS in Win2000 Server as a soft route, you can also use ISA2004, Winrouter Firewall, and other software. In Linux, there are also RouterOS, Smoothwall, m0n0wall, Coyotelinux, Ipcop, and so on. I hope this article will provide a reference on how to set up a soft route when you are new to soft routing.
