The VPN configuration of the Cisco router is not important for network security, but also makes the user more convenient during use. In this experiment, we use the Cisco 2600 router and the Cisco router VPN configuration to implem

At present, China's wireless router industry is developing very rapidly, and its market demand is also very high. Here we mainly introduce Cisco's first dual-band wireless router launched in China, this section describes the features and performance of the vro. In May 19, Cisco launched the Linksys by Cisco dual-band w

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 series routers running 7000 versions of Cisco IOS systems. Implementation steps: 1. Connect a terminal at the console port of the router or a

Initial installation of the CISCO router tutorial During the first installation, the system automatically enters the Dialog Setup, as prompted on the screen, answer the router name, encrypted super login password, super login password, remote login password, dynamic routing protocol, and the configuration of each interface, and save the configuration. After the v

I. Overview: In the actual work can often see a strong SSL VPN can bypass deployment, and support routing mode and NAT mode: Router mode requires intranet to VPN assigned address pool address can be router; NAT mode, VPN Client access intranet host, intranet host sees address as VPN interface address, Therefore, the address intranet of the VPN address pool is not required to be routed. If you want to test

The market demand for Cisco routers is still very high, so I studied the knowledge about the default password of Cisco routers and shared it with you here. I hope it will be useful to you. The following are some default initial IP addresses, user names, and passwords used for Factory installation of ADSL, which must be known for debugging. There are three methods to debug these settings: One of the most c

Cisco routers are widely used in network interconnection. Among them, 2500 series routers are widely used in low-end users. So what if you accidentally forget the superuser password of the 2500 series router? Don't be afraid, as long as you can restore as follows:Preparation: a computer running Terminal simulation program can start a Super Terminal in Windows 95/98), and the microcomputer serial port COM1/C

Cisco router Entry 1First, let's take a look at the Memory RAM of one of the vro's internal components: Random Access to the memory, which is equivalent to the memory of the computer and is volatile (all storage content will be lost after power failure ), the main software running is the IOS image and configuration file. ROM: read-only memory, which resident some microcodes used to start and maintain basic

The Cisco router NAC solves the problem. The so-called NAC is an architecture that allows multiple hardware and software components to work together to protect the user's network from adverse client attacks. 1. It is not easy to fully implement NAC, because the entire architecture contains too many different components from other vendors. For example, the architecture contains the NAC Policy Manager and mul

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
