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

Cisco router security-TCP connections are common attacks on the network. In fact, most attacks are based on TCP connections, and a large amount of request data is sent to cause Server Denial of Service, is a connection attack. Next, I will take a Cisco router as an example to introduce how to intercept illegal TCP conn

(This case uses two cisco2500 routers, IOS (tm) 2500 Software (C2500-IS-L), Version 12.2 (15) T9, the interconnection between two remote ipv6 subnets can be achieved by using the ipv6 v4 trunk and ipv6 6to4 tunnel combined with ipv6 Static Routing. Topology Description: Use the e0 interface of the two routers to interconnect and simulate the ipv4 trunk. Use loopback0 to simulate the two remote ipv6 subnets, 6to4tunnel must use the standard ipv6 address prefix (2002:/16) in all ipv6 subnets. Whe

This article uses a specific example to illustrate how to configure the access to ADSL through the vro. What problems should we pay attention to during access? The following articles will benefit you a lot. Note: In this case, a common adsl modem and a cisco 25001841) router (dual Ethernet port) and IOS 12.2 (15) T need to be used to connect to the China Telecom adsl PPPoE, able to achieve LAN Internet shar

With the development of China's routing industry, Wireless routers are also widely used. Here we mainly explain a new Wireless-N Wireless router launched by Cisco, cisco Wireless Router WRT320NWRT320N is the latest Wireless-N Wireless router launched by Linksys. This product

There are still many things worth learning about the Cisco router configuration mode. Here we will mainly introduce how to enter the detailed steps of the Cisco router configuration mode. In the Cisco router configuration mode, th

mpls vpn model consists of three components: CE, PE, and P:CECustomer Edge): It is a user's network Edge device. interfaces are directly connected to service providers, such as routers or switches. CE "perceives" that the VPN does not exist.PEProvider Edge) vro: the operator's Edge router. It is the Edge device of the operator's network and is directly connected to the user's CE. In the MPLS network, all VPN processing occurs on the PE router.PProvid

How should we connect to the Cisco router port? Many people want to know the specific role of the control port and the Auxiliary port. The port content is not detailed on the network. Here is just a few words about the port. The Cisco router port has a control port: the control port console port) and the Auxiliary port

It is very important for Cisco router users to learn about commands for password recovery of Cisco routers. For many beginners, the ROM Monitor of Cisco routers is often unfamiliar or even daunting for a simple reason, first, we do not often use this mode and are not familiar with its related operations; second, Operat

Netizens have their own preferences for Cisco router simulation software. The following describes three software models. I hope you can give it a try and give it a better reference to more friends. Everyone should know that the price of a router is very expensive, and it is very expensive to build a router lab. Howeve

Many people may not have a special understanding of Cisco router configuration, so I have studied the detailed knowledge of Cisco router configuration. I will share it with you here, hoping it will be useful to you. Have you ever encountered a situation where you have modified the
