We should also have mastered the IT migrant workers have four major skills: open equipment, pick up the line, set the address,ping got IP. Let's take a look at how static routing is set up, and how to make the addresses of different address segments interoperable. based on the information given by the map splash, we have configured the ports for the three

Before connecting, you can use a single machine to connect to router 2nd to see the instructions for two routers. If their default IP is the same, modify the

Router Introduction
A router (Router, also known as a pathfinder) is a computer network device that transmits packets to a destination via a network (selecting the transmission path of the data), a process called routing. Routers are devices that connect more than two individual networks, and routing works on the third layer of the OSI model-the network layer, such as the Internet Protocol (PROTOCOL,IP) la
Routers have a pivotal position in computer network, and are the bridge of computer network. It can not only connect different networks, but also choose the path of data transmission, and can block illegal access.
The configuration of routers is not very easy for beginners. Now the general configuration of the router and simple debugging introduced to everyone,
written as http://, with a colon: instead of a dot.: http.//192.168.1.1
The correct access method is input: http://192.168.1.1 or http://192.168.0.1 (HTTP can be omitted, that is, directly enter 192.168.1.1 or enter 192.168.0.1). Note that different brands of routers, the default IP access address is also not the same, and generally allow users to modify the default address. Therefore, please refer to the instruction manual for the specific acce
In recent years, the development of the Internet has been very rapid and applications have become increasingly commercialized, making it difficult to predict the development of the number of online users. In addition, more and more users need high-speed access. According to relevant information, the slow speed of Internet access is the primary cause of complaints from many netizens. Therefore, it is increasingly important to improve network bandwidth, network service quality, and network managem
Routers play an important role in the internet cafe network environment, but also often encounter many problems. Here we mainly analyze how the Internet cafe routers solve frequent disconnection problems. Currently, Internet-based applications of Internet cafe users have expanded from simple web browsing to more extensive fields such as QQ chat, VOD on demand, online games, education and training, and IP ph
At present, most broadband routers are stupid products. Users only need to understand some computer knowledge and simply take a look at the instructions to achieve Internet sharing through network connections. However, for some new users, you should pay attention to the following issues.1. connection to a computer or vswitch The lanports of a Broadband Router can be connected either directly to a computer or to a collection line device (HUB or switch
The modular router plays an important role in the development of the network. Today, I will explain the main advantages of the modular router. With the development of network technology and the expansion of network services, IP technology and broadband services have higher requirements on routers in terms of reliability, interface density, flexibility configuration, data packet forwarding speed, and multi-service.
In today's networks, modular
Preface
In the current enterprise network, most of the wired networks are affected by factors such as investment cost and transmission speed. Vro is an important bridge connecting local networks to external networks. It is an indispensable component in the network system and a cutting-edge entry in network security. It is very important to improve its performance.
More and more functions of current vro devices are implemented in hardware mode. The improvement of CMOS integration technology enabl
. Third trick: Turn off or modify the SSID nameThe SSID is the name of the wireless network that appears when searching for a wireless network. For enterprise users, the name is designed to make it easier for employees to find and connect to their own corporate wireless networks, but for individual home users, exposing the SSID only leads to illegal intruders. Therefore, turning off SSID broadcasts is also a good way to improve the security of your

Four, ISP binding MAC address caused unable to connect
Some broadband providers bind MAC addresses to the authentication server in order to limit the number of access users. At this point, the computer that is bound to the MAC address can be connected to the router LAN port (but the router does not
Vro is the core device in the network. The hardware router is familiar to everyone, and the most typical is the Cisco Series router. Software routers are emerging products, such as the WinRoute Pro software router launched by tiny software and the Internet gateway software router launched by vicomsoft. Compared with a software-based Router, some people think that Cisco products are purely hardware-based routers
At present, the development of routers, switches and hubs is very rapid, and the technology is more standardized and mature. First, the HUB, that is, the HUB. Its function can be simply understood as connecting some machines to form a LAN.
The switch, also known as the switch-type hub, works basically the same as the hub. However, there is a difference between the two in terms of performance: the hub uses the shared bandwidth method, while the switch
follows:Router #Interface ethernet 0Ip address 200.2.2.1 255.255.255.0Interface serial 0Ip address 200.8.8.1 255.255.255.0Router ospf 108Network 200.2.2.0 0.0.0.255 area 0Network 200.8.8.0 0.0.255 area 1
The IP address of Ethernet port 0 is configured in the first section, the IP address of serial port 0 is configured in the second section, and the OSPF routing protocol is started in the third section. The networks 200.2.2.0 and 200.8.8.0 are placed in different network domains respectively.

With the rapid development of the IT industry, Cisco routers are widely used in all walks of life. This article will start with the basic configuration and briefly introduce the configuration method of Cisco routers.
1. Configure the Ethernet port # conf t
Configure the router from the terminal (Cisco commands can be abbreviated as "conf t", as long as they are not repeated with other commands. For ex
Upgrade the old hub in the lab to a product of 10 m which should be obsolete. The network speed has been limited.
So today I bought three new mercury routes, 100 M and 8. It's silly to connect it back. We all have a fixed IP address. After changing the route, you can only access the IP address in the LAN of 192.168.1.1.
I have been living in an engineering male. When I encounter an electrical appliance, I will first study the product manual. If I en
Surfing the Internet makes it necessary for us to deal with broadband routers. However, during our use process, we seldom look at it. Even if the network is faulty, few believe that these faults are related to routers. In fact, a vro is the same as other network devices. When we set or maintain the router improperly, it may encounter various inexplicable faults. The most direct impact is the speed of our In
At present, ADSL permeate every corner of our lives, whether it is enterprises, Internet cafes, or home users using ADSL to access the Internet, usually, an ADSL line can only support one computer to access the Internet, however, after using a networking device, you can implement an ADSL line to support Internet access shared by multiple computers. Generally, devices that implement the shared networking of ADSL include ADSL Modem, Broadband Router, and switch. A few days ago, a user asked the fo
