Router is the bridge of computer network, is the core device of connecting IP network. It can not only connect different networks, but also choose the path of data transmission, and can block illegal access. Routers are data packet forwarding devices that work in the third layer of the OSI Reference Model-the network layer, and routers implement network interconnection by forwarding packets. For beginners, routers are not easy to configure. This paper
First, Introduction HSRP (hot Standby Router Protocol Thermal Backup Router protocol) is a proprietary protocol of Cisco. HSRP makes up a "hot backup group" of multiple routers, forming a virtual router. Only one router in this group is active (active), and it forwards the packets, and if the active
At present, PE routers are widely used. They are one type of VPN routers. So I have studied the explanations and principles of PE routers and will share them with you here, I hope it will be useful to you. VPNVirtual Private Network (VPNVirtual Private Network) is a virtual Private Network based on public networks. It uses tunneling, encryption, and other technologies to provide users with a sense of direct connection to the Private LAN.

When using the LAN router configuration method, the LAN router configuration method is often optimized, as well as the WAN port connecting to the wireless router and related problems. Here we will introduce the solutions to many problems involved.
Summary: Lan router configuration methods
With the popularity of wireles
Network Transmission of some key business data of some enterprises or organizations requires high reliability of network equipment and convenient maintenance.
There are multiple backup technologies for Cisco routers. Here we will introduce the router's own backup technology and line backup technology.
Generally, a router is a bridge between a LAN and a wan.
The so-called router's own backup technology is designed to solve a router's own hardwa
OSPF router type When an AS is divided into several OSPF regions, OSPF routers can be classified AS follows based on the role of a router in the corresponding regions:Internal router: When all the directly connected links on an OSPF router are in the same region, we call this route
Router hardware Extraction
In the previous chapter, we have learned how to extract the root file system from the router firmware, and how to analyze and mine vulnerabilities. Starting from this chapter, we will learn some basic knowledge about router hardware. Generally, we obtain available firmware from a vro manufacturer. However, not every vro manufacturer pro
There are multiple backup technologies for Cisco routers. Here we will introduce the router's own backup technology and line backup technology.
Generally, a router is a bridge between a LAN and a wan.
The so-called router's own backup technology is designed to solve a router's own hardware (such as memory, CPU) or software IOS fault or local port fault, network breakdown caused by the failure of the port or line of the connected local area device.

Currently, there are many kinds of router protocols, and many people may not know how to use the Router Protocol to minimize network interruptions. It doesn't matter. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. As we all know, to obtain a high network duration, you need to use a master router
In order for the wireless router to work correctly as specified, we often need to log on to its backend admin interface through Web Access before using the device, and make appropriate settings for its Internet parameters. Generally speaking, ordinary users only need to modify the user name and password in the background, and follow the instructions to install and use the wireless router; But in the actual

Many junior network administrators ignore security settings when using Cisco routers, and the following three are ideal for novice users to configure network security when using Cisco routers.
One, the security configuration of the router "access control"
1, the administrator who can access the router is strictly controlled. Any maintenance needs to be documented.

Because of the continuous advancement of social informatization, people's demand for data communication is increasing. Since the launch of TCP/IP protocol cluster in the 70 's, it has developed into the fact standard of Network layer communication protocol, and the Internet based on TCP/IP has become the largest and most important network. As the core equipment of IP network, routers have been widely used.
As the core equipment of IP network, the technology of
If a Cisco Wireless Router is improperly configured, problems such as disconnection and disconnection may occur. It is very important for us to have a deep understanding of the details in Cisco wireless router configuration. Next we will introduce the relevant knowledge in detail.
As we all know, wireless signals are the carriers of data transmission, which means that the stability of wireless networks has
A home broadband router is a broadband router with a smaller number of users, such as a 4LAN-port router, which allows 4 computers to surf the internet at the same time. If a home/dormitory/small office has multiple computers that need to be connected to the Internet at the same time, using a router to form a small loc
Broadband routers are still commonly used. So I have studied the optimization techniques of broadband routers. I will share them with you here and hope they will be useful to you. Surfing the Internet makes it necessary for us to deal with broadband routers, But we seldom look at it during our use.
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
At present, broadband routers are widely used. Here we will mainly explain the optimization technology of broadband routers and surfing the Internet, so we will inevitably deal with broadband routers, but in our use process, I 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
