VPN, as we all know, is a virtual private network, and I am too lazy to heap up a bunch of technical terms to test your language capabilities. Simply put, it is to use a public network to achieve remote access to the private network, for example, we know that many enterprises use the Intranet, so what if employees are on a business trip or want to access the company's network? VPN can solve this problem wel
Free and available IPv4 addresses will soon be "exhausted". Over the years, this has prompted most general operating systems to begin to add IPv6 support. However, many applications (such as VPN clients and server software) are not ready for IPv6. This will lead to the situation where the dual-protocol stack host deployment does not support IPv6 VPN software, thus opening the door for security vulnerabiliti

Label structure:
The label field of 20 bits is used to indicate the label value. Because the label is fixed length, you can analyze the label of a vro to forward data packets. This is the biggest advantage of label exchange, the Fixed Length Label means that data forwarding can be implemented using hardware. This hardware forwarding method is much more efficient than

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 proceed smoothly, first requires the virtual route with ASA and Cisco router to establish

Comparison and Analysis of mpls vpn and VLAN + ACL
Scope of application: VLAN is essentially a LAN technology and is suitable for LAN isolation. However, VLAN alone cannot guarantee the isolation of IP services and must be used with ACL. In this way, all business systems are in the same IP address space, which is visible to each other and not truly isolated, leaving hidden risks for network security. Mpls vpn

VPN is a secure and stable tunnel through a chaotic public Network. Through packets and encrypted transmission of network data, a temporary and secure connection is established in a public network (usually the Internet, in this way, private data can be transmitted on the public network to reach the security level of the private network. If the access method is dial-up, it is called VPDN. Gene
