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

This article uses VPN technology to achieve interconnection between two parts of the network, simulate ISP, close to practicality, the article mainly shows us the specific operation steps, mainly the input of basic commands. In this experiment, we use the Cisco 2600 router and VPN technology to achieve the network interconnection between one branch and two parts. To stay close to practicality, we still use

Some time ago, someone familiar with me asked me how to set up a bridge on a Cisco router )? At that time, due to the relationship between work, I just briefly talked to him. Today, we set up a Cisco router as a complete configuration command for bridging. Through this instance, you can learn how to use a

address of the TFTP server be entered. After the Server IP address is correctly entered, the router also requires the network administrator to provide the configuration file name to be backed up. Generally, we recommend that you use a file name that is easily remembered by the Administrator. At this time, the router will prompt the Administrator to press YES to confirm the operation. 3. copy tftp running-c

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

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
