This is a professional article about Cisco routers. Students who want to learn this knowledge can get some reference in writing this paper. This article mainly describes the technical application of the Cisco router level-1 switch. The Network works on two devices. The vswitch and vro connect the computer with the peripheral device. These two tools enable communi

Nowadays, filtering network content is not only an optional action for enterprises, but also an action that enterprises must take to prevent employees from making mistakes. In this article, the author David Davis will explain how the Cisco IOS router uses third-party services to implement Web content filtering. To protect enterprise networks and end users from malicious or undesirable web content intrusion,

This article introduces the configuration and operation process of IOS upgrade against Cisco routers in two ways. Not long ago, when a friend upgraded CISCO2610 with a voice mode, the memory flash of the router was 8 MB, and the IOS software was more than 7 mb. After the upgrade, the router could not start normally. Go to the rommon 1 gt; status after startup to

There are many users who use Cisco routers, and there are also many problems. Password forgetting or loss is a common problem for users. So I studied the two methods for restoring the Cisco Router password, I would like to share it with you here and hope it will be useful to you. When a Cisco

The OSPF protocol is very important for the use of Cisco routers. But how do I perform specific operations? The following article will give a detailed explanation. OSPF protocol operation: 1. the ROUTER that declares OSPF sends a HELLO message from all interfaces that start the OSPF protocol. The two routers share a Public Data Link and can negotiate with each other the parameters specified in their HELLO p

This article describes in detail how to understand the technology of Cisco routers in terms of basic network equipment issues, regular system upgrades, and the use of Cisco routers. I believe you will be helpful after reading it. These two tools enable communication between devices connected to the network and other networks. Although vrouters and vswitches look very similar, they have different functions i

Maybe many people do not know the actual application of the NetEye firewall and the Cisco router. Next we mainly analyze the security problems of the NetEye firewall and the Cisco router. Firewall has become a key part of enterprise network construction. However, many users think that there are already routers in the n

Self-contained AAA router/NAS self-contained AAA service NAS (Network Access Server) 2. Contact the

A Cisco router is a network device that connects multiple networks or CIDR blocks. It can translate data from different networks or CIDR blocks ", so that they can "read" each other's data to form a larger network. A vro consists of hardware and software. The hardware is mainly composed of physical hardware and circuits such as the central processor, memory, interface, and control port. The software is main

For common users, it is necessary to learn how to back up the Cisco router configuration file to ensure the security of our routers. In recent years, many cities have established urban financial networks. The construction of these networks has promoted the construction of electronic finance in various regions. Vro is a key device of the city financial network and a bridge to the computer network. It can not

Using the Cisco router configuration can easily implement VoIP, So I studied the statements related to the Cisco router configuration and shared them here, hoping to be useful to everyone. VoIPVoice over IP) is a technology that transmits voice over the Internet. It has grown with the development of Internet technology

When a Cisco router forgets or loses the enable password, there are two ways to recover, depending on which series of routers you are using. The first of these methods This approach restores the following routers: Cisco 2000 series, 2500 series, 3000 series, Cisco 4000 series using the 680x0 Motorola CPU, and 10.0 se

I have learned some useful questions about the password of a Cisco router. So I have studied how to use the password to protect a Cisco router. I would like to share it with you here and hope it will be useful to you. The most serious cause of security problems is often because people ignore the most basic security mea

principle, using a Udpecho request instead of a ICMPECHO request to initiate an attack. While cyber security experts are focused on developing devices that block Dos attacks, they have little effect because Dos attacks exploit the weaknesses of the TCP protocol itself. Properly configured routers can effectively prevent Dos attacks. In Cisco routers, for example, the iOS software in Cisco routers has many

Router Access ADSL configuration detailed 1, Cisco router connection to the ADSL modem configuration: Note: The case for Beijing Telecom ADSL PPPoE access, need to use a common ADSL modem and a Cisco 2500 router (dual Ethernet port), IOS 12.2 (T), Be able to realize LAN sha

Global debugging When configuring a Cisco router, the boundaries between global and interface commands are obvious. In this case, we use "Global" to identify commands that cannot be used for interface debugging or specific transmission media types and Protocol debugging. For example, in vrouters 2500, you can use Debugging commands to analyze the Cisco Discovery
