cisco 2811 router configuration examples

Configuration purpose: The Register configuration is used to change the router startup process. The start bit is made up of 4-bit 16-digit registers Format: 0xABCD Assignment range from 0x0 to 0xFFFF 0X2102: Industrial Default value 0x2142: Starting from flash, but not using the configuration file in NVRAM (for Su

I. Overview: Cisco 15.2 iOS support IKEV2 IPSec VPN, security is more IKEV1, the first phase of authentication methods also have a variety of ways to support the local and remote use of different authentication methods, this test for both sides both local and remote use of preshared key method. Two. Basic ideas: The A.VPN peer is configured with a static VTI mode while the dynamic VTI mode is used. B. The actual test found that the VTi interface c

This article describes in detail how to configure PPP authentication and CHAP authentication, and provides the command line for configuration. You can learn about the configuration process through the instance. When configuring PPP verification, select PAP and CHAP. PAP is the user name and password for the plain text transfer, which is not secure. CHAP uses hash values for verification. Passwords are not t

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

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

In addition to address binding, ARP configurations of Cisco routers are getting more and more attention. Therefore, we will discuss two aspects here. It seems a bit messy, but I hope it will help you. I know that the command for binding the IP address of the cisco router to the mac address is arp IP address, mac address, arpa, but I think there should be a comman

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

NAT configuration on a CISCO router is in full swing and causes the shortage of IP addresses. to alleviate this problem, an important application is NAT (Network Address Translation ), it is widely used. Through address translation, NAT enables enterprises to access the Internet by using only a small number of valid IP addresses on the internet, effectively allev

I. Overview: Cisco routers have a lot of IKEV2 for the IKEV2, so you can configure them with little configuration. Two. Basic ideas: A. Configure flex VPN on both sides in a svti manner B. No dynamic routing, configuration of static routes, if one side with Dvti, you need to configure static routes on both sides Three. Test topology: Four. Flex VPN

Cisco single-ARM routing configuration One-arm routing, which is to set up multiple logical subinterfaces on the router, one VLAN for each sub-interface. The data on each sub-interface is passed on the physical link to be labeled encapsulated. Cisco devices support ISL and 802.1q (dot1q) protocols. Huawei only support
