how to configure ipsec vpn on cisco router

This site has previously shown us the method of segmenting a router into eight virtual routers using virtual Routing and forwarding (VRF, VM forwarding) through a scene example. I showed you how to configure VRF, and in this article we continue to use this scenario and, through IPSec configuration, replicate the exact topology and address to eight experimental environments. The entire environment can procee

is not supported; (Mobike allow IKEv2 for mobile platforms, such as mobile phones, etc.) The IKEV2 has built-in NAT traversal capability, while IKEV1 is supported by the extended protocol; The IKEV2 can detect the tunnel survival state, while IKEV1 can only use DPD (Dead Peer Detection). DPD has become the standard built-in function in IKEv2. However, the Cisco IOS system by default this feature is disabled, can be configured under the IKEv2 conf

R2 simulates a car

I. Overview:IPSec VPN has a variety of methods through NAT, NAT-T is one of them. Generally, IPSec VPN cannot cross the NAT device because the ESP traffic does not have a port number as the TCP or UDP traffic does. When the first phase of the test of IPSec VPN is aggressive-

The VPN configuration of the Cisco router is not important for network security, but also makes the user more convenient during use. In this experiment, we use the Cisco 2600 router and the Cisco

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 inte
