With the development of China's routing industry, it has also promoted the continuous improvement of router protocols. Here we mainly introduce the knowledge of router protocols that network engineers should have mastered. Distance Vector router protocols are designed for small network environments. In a large network environment, this type of

Introduction This document describes how to upgrade the Cisco IOS software image on the connected router platform. Upgrade instances of vrouters 2600 and 3600 are also applicable to the vro platforms listed below. The name of the Cisco IOS software file may vary depending on the Cisco IOS software version, function settings, and platform. This document describes the following Cisco Series routers: Cisco 1000 series routers Cisco 1400 series routers

Friends sent a WZR-HP-300NH buffalo router, but the system was brushed into openwrt, but also do not know the Administrator account Password = ... Brush the OPENWRT system, Buffalo router Restore factory Settings button also failed, is estimated to be openwrt system compatibility problem, can only be a way to re-brush the system.Google found the next TFTP brush tutorial, it was thought to be very simple thi

TP Router wr866n set up wireless bridge Step one, enter the management interface Primary and secondary routers through the wireless WDS Bridge, wireless terminals can connect the main and secondary routers online, mobile process can be automatically switched to achieve roaming. The topology is as follows. Attention 1, the primary and secondary routers do not connect network cable; 2, WDS Bridge only need to set up on the secondary

At present, wireless router has become a home wireless sharing and Internet application of the mainstream, about the use of wireless router is also a lot of users are very interested in, we will pick some of the more representative of the wireless router problem, for you one by one to explain its fault solution, I hope you can analogy. The wireless router's red

Subnet Mask hardware basic Ethernet protocol Network Management A router is a bridge of a computer network and a core device connecting to an IP network. It can connect different networks, select data transmission routes, and block unauthorized access. Router configuration is not easy for beginners. Take the Cisco router as an example to introduce the ge

China's vro technology is developing rapidly, and technological standards are also being innovated. So I have studied the basic knowledge and principles of vro technology. I would like to share it with you here and hope it will be useful to you. 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 proto

corresponding to the MAC address in the table, copy the packet directly onto the port. Three-layer switch: three-layer switching technology is the technology of combining routing technology with Exchange technology. After the first data flow is routed, the it will generate a MAC address and IP address mapping table, when the same data flow through again, according to this table directly from the two layer through rather than again routing, thus eliminating the

eliminating the router routing and resulting in network delay, improve the efficiency of packet forwarding. Routers: Traditionally, routers work in the third layer of the OSI Seven layer protocol, whose main task is to receive packets from a network interface and, depending on the destination address contained therein, decide to forward to the next destination address. Therefore, the router must first find

The routing technology must also comply with the router standard in its application. Although the current router standard is not complete yet, it is believed that with the development of routing, it will also be more improved and stable. Vro supports multiple protocols, such as TCP/IP, IPX, SPX, and AppleTalk. Even the TCP/IP protocol has versions 4 and 6. However, due to the fact that TCP/IP has become a s

With the development of wireless network, more and more companies and enterprises have begun to layout wireless LAN, today we mainly introduce the appropriate for small and medium-sized wireless router bridging or WDS capabilities. This article takes tp-link wr841n wireless router Setup as an example, and other router reference setup ideas to set up.As shown in a

Recently, I bought a new 705S wireless router, because my original wireless router is outdated, the following and netizens share the experience of the use of this router. Used to surf the internet quickly, online to see the movie very smooth, very few cards, download a few 10 trillion software 32 under the end, browsing the web is naturally not said, it is flyin

When the router is published, there are some technical terms, such as 802.11AC, 5G, gigabit, dual frequency, 2*2 antenna, Wi-Fi, and also the conclusion that "10 times times Faster", "Top Configuration", "Global X". Under the manufacturer propaganda, some people think that the product is good to be bad, also some people think the manufacturer is bragging x. This article is the wireless router knowledge popu

China's vro technology has developed rapidly and is widely used. So I studied the Functional Comparison Between BRAS and vrouters and the comprehensive comparison between the two technologies, I would like to share it with you here and hope it will be useful to you. To help telecom operators build an IP bearer network that comprehensively carries voice, data, video, and mobile services in the 3G era, it has become a trend to integrate BRAS and routers into the same network device, which brings o

For wireless routers, we have used them very frequently. But how can we set them during the networking process? What are the differences between our routers through a series of settings? As we all know, wireless signals are the carriers of data transmission, which means that the stability of wireless networks has a very direct relationship with wireless signals. In fact, to make the wireless router in a very stable state, you must make a series of rea

Hub, switch, router, working principle 1. A switch is also called a switch hub. It regenerates information and forwards it to a specified port after internal processing. It has the ability to automatically address and exchange information, the switch sends each information packet independently from the source port to the destination port based on the destination address of the information packet to avoid collision with other ports. A vswitch in the br
