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.

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
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
In today's information society, people are increasingly demanding data communication. As the core equipment of the IP network, vro has become a key technology in the information industry.Vro A router is a packet forwarding device that works at the network layer of the OSI reference model. The router forwards data packets to achieve network interconnection. Although routers support multiple protocols, such a
Wireless Router fault description
In practical applications, many users directly use the ADSL-related information after purchasing a wireless router. The following problems may occur:
"I use a wireless router to share the Internet. The speed is fast and slow !"
"My laptop is only 10 meters away from the wireless router
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

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
What does router hijacking mean?
Router hijacking, usually refers to the wireless network in the radio router, other users by cracking the wireless network password, thereby connecting to your wireless network, and then through the login router management interface to control the entire wireless network.

1, connect the router to the external network
Step one: Connect a good line
In the absence of a router, we are directly connected to the Internet through the computer to connect broadband, so now to use the router to share broadband Internet access, of course, the first to use the router to directly connect broadband
Due to the continuous advancement of social informatization, people's demand for data communication is increasing. Since the launch of TCP/IP protocol clusters in the middle of 1970s, it has become a factual standard for network layer communication protocols. TCP/IP-based interconnected networks have become the largest and most important networks. As the core device of an IP network, routers have been widely used.
As the core equipment of the IP network, vro has become a key technology in the in
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 some fault or local port fault
