An example of Cisco Easy VPN comprehensive configuration is shown in this example. The topology is 15-15. In this example, the Cisco 831 router is used as the remote device of Easy VPN and the

I came back again, the last two articles introduced the Huawei Stack, third firewall IRF. This time to introduce the Cisco stack (stack), although the implementation of the idea is consistent, but the configuration there is a need to pay attention to the place, especially now do the two-tier operators of the network workers, all the producers will be, the pressure is really big.First, the topological enviro

Vswitch span technology Overview + Cisco configuration example 1. Introduction to span The span technology is mainly used to monitor data streams on vswitches. It can be divided into two types: Local span and remote span.---- Local Switched Port Analyzer (SPAN) and remote span (rspan) have slightly different implementation methods. Using the span technology, we c

BGPIs the routing protocol used to connect to an independent system on the Internet. It is an enhanced, comprehensive, and scalable protocol developed by the Internet Engineering Task Group. BGP4 supports the CIDR addressing scheme, which increases the number of available IP addresses on the Internet. BGP was designed to replace the original external gateway protocol EGP and is also considered a path vector protocol. The reflector

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 Int

router security management, and provide users with comprehensive online help and guidance. The Cisco SDM smart wizard guides you through systematic configuration of LAN, WLAN and WAN interfaces, firewalls, intrusion prevention systems (IPS), and IP Securtiy (IPSec) VPN to gradually complete the router and router security configuration. The

.png"/> Configuration Requirements: The interface IP addresses must be configured for different systems in Figure 1, and the dynamic routing protocol RIP must be enabled for different systems, it also requires that each IP node in the network environment can communicate with another IP address. Use ping to view the route table of each route device as the verification result. Configure teaching and demonstration resources:Hybrid

The market demand for Huawei routers and CISCO routers is very high. So I studied the differences between the configurations of Huawei routers and CISCO routers. I would like to share with you here, hoping to help you. The features and configuration interfaces of Huawei routers and CISCO routers of the same grade are e

There are many things worth learning about in the configuration of a Cisco Wireless Router. Here we mainly introduce how to use a vro to set up a PC to share the Internet, including knowledge about DHCP, security, TCP/IP network protocols, and so on. As a product designed specifically for broadband Internet sharing, a Broadband Router has the advantages of simple and convenient Internet sharing, high securi

The features and configuration interfaces of Huawei routers and CISCO routers of the same grade are exactly the same, and some of them have also been improved according to the needs of domestic users. For example, the configuration and debugging interface that can be switched between Chinese and English makes Chinese u

is encrypted during network transmission, strict control is required. For example, set a strong password, control the number of concurrent connections, strictly control the access address using the access list, and set user access control using AAA. 1. We recommend that you enable IP Unicast Reverse-Path Verification. It can check the accuracy of the source IP address and prevent certain IP Spooling. However, it can only be used on routers that enabl

Comments: This article describes the basic configurations of Cisco routers. The configuration process of Cisco routers is still complicated, and there are many factors to consider, especially in terms of security. In fact, there is no need to make the router think so complicated. In fact, the router is a computer with multiple ports, but it plays a different role

This article mainly introduces how to configure the vro for Cisco IOS configuration lock to prevent configuration disorder. I believe this article will help you. If multiple network administrators connect to the vro at the same time to modify the configurations, the changes may be lost or only part of the content can be executed, resulting in problems in the oper

that you need a user and a password to gain access. In addition, we recommend that you use a secret password for your username, instead of a common password. It uses MD5 encryption to encrypt passwords, and greatly improves security. Example: Router (config) # username root secret My $ Password After the user name is configured, you must enable the port using the user name. Example:◆ Router (config) # line

Users using Cisco routing, many of them do not pay much attention to doing Cisco router configuration work, in fact this is a very important part, especially for our network security. There are several ways to do Cisco router configuration. The

Client list: You can view all active users of the Cisco wireless router configuration through the client list function.Static Address Allocation: Through the static address allocation function, you can specify an IP address for the PC on the vro side and an IP address based on the MAC address of the NIC on the PC side. 4. Set forwarding rule options When accessing the Internet through a router, all clien
