Cisco configuration instance _ Cisco dual-Egress NAT configuration objective: to simulate the routing function based on the original address policy when a dual-Egress link is available, and access to the external network from different original addresses is realized, in most cases, the vro uses NAT to translate the Intranet address on the external port, so this experiment also uses dual NAT to translate the

Introduction after you log in to the CISCO switch, we will need to use some common operations, such as querying, restarting, and so on, where some of the commonly used operations are grouped together. Query HelpIn different modes, we can enter the question mark directly (? You can query all the commands that you can use in the current mode. When entering a command, if you do not remember the full name of the command, enter the first few characters

LAN is not changed, and the configuration and access control list of the external network Port WAN needs to be changed .Increase the configuration of the VPDN. Assuming the username is admin, password 123456, the configuration process is as follows:This case is XX Telecom ADSL PPPoE access, need to use a common ADSL modem and a Cisco 2600 router (dual Ethernet port), IOS 12.2 (), can realize LAN sharing Internet.　　This case configuration is divided i

Tags: process proc ima RAC Technology share static term ADOBy configuring static routes, you can achieve an increase in routing entries for routers in a relatively simple network.However, if there are more than 20 routers in a network, it is difficult to configure static routes to accommodate the complexity of routing entries and changes in the network. At this point we can use the RIP protocol to configure simple dynamic routing, thus reducing the workload.Configuration ideas1 Configure the IP

What are the implementation methods?NAT (Network address translation): By translating the private IP address of the internal network into the world's only public IP address, the internal network canTo connect to an external network such as the Internet.How NAT is implemented:The corresponding relationship of the IP address is one-to-one, and is constant, with the help of the static transformation, it can realize some specific service in the external network.Access to the se

The loop has a great impact on the network. Spanning Tree protocol is a good solution to this problem.The idea of spanning a tree protocol topology is that, regardless of the physical connection between switches, the switch can automatically discover a network with no loop topology, and the network of the logica
