RIP and IGRP are commonly used router configuration protocols. What problems should we pay attention to when configuring RIP and IGRP? What should we do? The following configuration steps provide detailed answers. RIP Protocol RIP (Routing information Protocol) is an Internal Gateway Protocol (IGP) that is widely used earlier and is suitable for small-sized similar networks, is a typical distance-vector protocol. For more information, see RFC1058 an

Preparation Tools Cisco TFTP server, HyperTerminal, iOS files iOS files are not easy to find, you need to look at the hardware version, as well as the size of ROM RAM, to my Cisco 2621XM for example (with two fastethernet),Start looking for a few 2600 of iOS, the brush is not correct, the problem of unrecognized network interface, can not be configured, there should be F interface with S Ios,

A Cisco router is detected infected with a secret backdoor. Security company FireEye researchers reported that backdoor programs called SYNful knock were found on 14 Cisco routers in 4 countries. Cisco has confirmed this. The attack does not take advantage of the vulnerability of the product itself, but requires valid

. RPF reverse transmission path forwarding) is an input function activated on a network interface or sub-interface to process packets received by the router. It is very important to enable the CEF function on the vro, because RPF must rely on CEF. Unicast RPF is included in Cisco IOS 12.0 and later versions that support CEF, but does not support Cisco IOS 11.2 or

CHAP (Challenge Handshake Authentication Protocol) and PAP (Password Authentication Protocol) are generally used to provide security Authentication on PPP encapsulated serial lines. With CHAP and PAP authentication, each Cisco router is identified by a name to prevent unauthorized access. Task commands Set the PPP encapsulation ppp1 Set the authentication method ppp authentication {chap | chap pap | pap cha

This article describes how to control the BT traffic of a Cisco router through specific operations, and describes the specific operation methods in detail. I hope this article will help you. Network-Based Application Recognition (NBAR) indicates Network Application Recognition. NBAR is a technology that can dynamically search for protocols in Layer 4 to Layer 7. It can not only control static and simple net

are used The route of this packet. ---- GRE only provides encapsulation of data packets. It does not have encryption to prevent network listening and attacks. Therefore, in the actual environment, it often corresponds to an IP address. When the SEC is used together, IPSec provides encryption of user data to provide users with better security. The GRE protocol has two main purposes: internal protocol encapsulation and private address encapsulation. In China, CEN uses almost all TCP/IP protocols,

Probably a lot of people on the Cisco router speed limit is not a special understanding, so I studied the Cisco router speed limit detailed settings statement, here to share with you, I hope to be useful. In a Cisco router device,

CISCO router device categoryThe name rules of cisco routers start with cisco, such as cisco2611 and cisco2610. cisco is the name of the device manufacturer, 26xx represents the 2600 series routers, and xx is a more detailed classification. The following lists several common

Experiment Name: Cisco router network address translation (NAT)Experimental purpose: To achieve all intranet IP to use a small number of public IP network connection to the InternetExperiment Introduction:With the help of NAT technology, when the intranet private address sends packets to the router, the private address is converted to a legitimate public IP addre

This article describes how to enhance the security of a Cisco router by using a Nipper. So how should we use it? The following article gives you a detailed answer. How do I use a Nipper? Since Nipper supports so many devices and is also known to support a wide range of multi-functional options, it is impossible for me to present them in all aspects. However, we can make a basic demonstration. In our example

One. Test the topology:650) this.width=650; "src=" http://s3.51cto.com/wyfs02/M02/6E/CA/wKiom1WH46fhBjvJAADX2zoss3k937.jpg "title=" TP1. JPG "alt=" Wkiom1wh46fhbjvjaadx2zoss3k937.jpg "/>Two. Test ideas:A. Enable resolution by IP NAT without setting the direction---this way can be accessed directly from the public IP address, or can be accessed by domain name method---unfortunately Cisco is different iOS, some although have IP nat enable, but do not re

Necessity for configuring WRED on a Cisco Router Although the queue provides VoIP QoS congestion management, it still needs some congestion avoidance mechanisms, such as WRED. In particular, WRED can prevent the output queue from reaching the limit value, which will lead to the loss of all input packets. This article comes from Informit and discusses the necessity of configuring WRED on a

supports SSH. log on to your vro or vswitch and check whether you have loaded an IPSec IOS image that supports SSH. In our example, we will use the Cisco IOS command. Run the following command: Router> Show flash This command displays the name of the loaded IOS image. You can use the result to compare the list of supported features of your supplier. After you verify that your device supports SSH, make sure

1. Password Recovery Principle 1) The Cisco router stores several different configuration parameters and stores them in different memory modules. The memory of Cisco Series routers includes ROM, Flash memory, RAM, immutable RAM, and Dynamic memory DRAM. See table 1 ). Generally, when a vrodram starts, it first runs the program in ROM, conducts system self-check

Cisco once again launched a new generation of router products and also applied new technologies. So I studied how Cisco developed the new VQE technology to solve the problem of IPTV Video Delivery. Here I will share it with you, I hope it will be useful to you. Cisco has announced the release of the VisualQualityExperi

Cisco IOS is a dedicated kernel that provides routing, switching, network interconnection, and remote communication capabilities. Most Cisco routers are running iOS, and more and more Cisco Catalyst switches are running it, including Catalyst2960 and Catalyst3560 series switches. Some important aspects of the Cisco

The rapid development of wireless networks has also promoted the wide application of wireless routers. At present, the market demand is also very high. Here we recommend a Cisco wireless router, cisco's Linksys wireless products have always maintained Cisco's high quality. As a result, this WRT54GC Cisco Wireless Router
