In Cisco router configurations, NAT configurations are frequently used. I hope the introduction below will be helpful to the majority of fans. It is a common method. The vro performs simple NAT translation and sets a CIDR Block in the NAT address pool. After a while, I found that the address pool was a waste of time. When I wanted to use a real ip address, I couldn't use it, so I decided to modify the
Use the tftp function of Linux to configure information about cisco router-Linux Enterprise Application-Linux server application. The following is a detailed description. In a LAN environment, if there are Cisco routers and Linux servers. Maybe you need to use Linux

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
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
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

I want to back up the running-configure configuration. Of course, the device has been configured and the tftp server is ready. The Cisco router configuration is as follows:

I want to introduce a Cisco router simulation program to you today. I hope that a friend who is looking for software can take a look at this article to avoid some unsuitable factors after you download it. Software type: domestic software, authorization method: Shared Software, interface language: Simplified Chinese, Software size: 32.5 MB, file type :. exe, running environment: Win2003, WinXP, Win2000, Win9
There is a bit of crooked nuts on the forum sigh "Cisco router QoS project monitoring is always painful", admittedly, the general router traffic monitoring, using cacti to do, and due to the different upgrade version number, and the router iOS version is different, and very difficult, Some programs even need to TFTP do

Cisco router configuration manual Virtual LAN (VLAN) routing 1. The main network technology we currently use when constructing an enterprise network is generally based on exchange and virtual networks. The exchange technology changes shared media to exclusive media, greatly improving the network speed. The Virtual Network Technology breaks the restrictions of the geographical environment. without changing t
Cisco router has become a commonly used network device, but we are not very clear about its storage classification. Here we will introduce it in detail.
Memory category:
1: RAM: Random Access to memory, equivalent to computer memory
2: ROM: read-only memory. Some microcodes used to start and maintain the router are resident in the ROM.
3: FLASH Memory, equiva
: single two-way authentication: www.2cto.com 2.2, CHAP authentication: CHAP: Challenge Handshake Authentication Protocol, full name: challenge Handshake Authentication Protocol. CHAP verifies the identity of the authenticated end through a three-way handshake. It is completed when the initial link is established. To improve security, it is periodically verified after the link is established. CHAP is safer than PAP because CHAP does not send plain text online, but instead sends a random number s
router. PDLM is written by the Packet Description Language Module, which means the data Packet Description Language Module. It is a description of the protocol layer of high-level network applications, such as the protocol type and service port number. Its advantage is to adapt NBAR to many existing network applications, such as http url, DNS, FTP, and VoIP. At the same time, it can also be defined, to enable NBAR to support many emerging network app

Default route Configuration
The default route is generally used in the stub network, and the stub network is a network with only one egress path. Use the default route to send packets that are not included in the route table of the target network. In fact, you can understand the default route as a static route with a wildcard (wildcard.
