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 configuration: A.R2: Crypto IKEv2 Keyring Keyring Peer 202.100.2.1 Address 202.100.2.1 Pre-

Environment Cisco 2500 Series Router Problem with Cisco router password recovery The Cisco 2500 router has several passwords, including the Enable secret,enable password,telnet password, and so on. The Enable secret is the most important, the password must be forgotten after the use of extraordinary means to recover. The following is a brief description of the

The previous one to everyone talked about the basic operation of Cisco switches, before the Dragon Boat Festival holiday, the Cisco switch to share a simple configuration and wish you a happy Dragon Boat festival! Ok, to configure the switch, you must first enter the switch's global configuration mode, successfully connecting to the switch and landing successfully into privileged mode 1, input into the glo

Cisco Firewall ASA Configuration case Topology map Requirements: Through Cisco Firewall ASA use intranet users can access the external network and the server in the DMZ, the server in the DMZ can be published to the network, for the extranet user access A The use of Cisco analog firewalls Because we do not have real equipment, we use a virtual system using

Global debugging When configuring a Cisco router, the bounds of global and interface commands are obvious. In this case, we use "global" to identify those commands that cannot be used for interface debugging or for specific transport media types and protocol debugging. For example, in the 2500 series router, you can use the Debug command to analyze the Cisco Discovery Protocol (

He is a proprietary technology of the Cisco platform and is the private protocol of Cisco.In layman's terms, a local area network has two routing devices connected to the extranet, one as a host and a backup. Normally the primary (active) router works. When the primary router fails, the backup (standby) router

Let's talk about Cisco Huawei and Intel vswitches. The vswitches with Intel are the same as those with other settings. This article mainly introduces the comparison of Cisco, Huawei, and intel vswitches. How to Set Intel vswitches has become a concern. This article provides an in-depth explanation of vswitches in terms of principles, ideas, and testing processes. Compared with

Cisco LAN switches are still commonly used. So I studied the maintenance and configuration problems of Cisco LAN switches. I would like to share them with you here, hoping to help you. Cisco LAN switches have evolved from a HUB-based LAN shared in the traditional sense to a broader space. Take Cisco's ipvst5000 series Cisco
