Centos7 enables IPv6 users to surf the Internet, parse dns and visit websites.

In recent years, the state has made great efforts to promote the construction of IPv6, and the government, institutions and state-owned enterprises have taken the lead to respond, and began to explore and learn the application of IPv6 in the current network. According to the current contact with the customer requirements, specially set up the following environment learning test.

The topology environment is as follows:

Centos7 enables IPv6 users to surf the Internet, parse dns and visit websites.

Configuration steps:

1. The whole network ospf and ospfv3.

two。 Configure dhcp configure dhcp on top of dns-master so that client1 and client2 can get the address

3. Configure web-nginx, which can be accessed through IPv4 and IPv6 addresses

4. Configure dns-master master dns and dns-slave slave dns to give web-nginx a www.langqun.com domain name, which can be accessed on client clients through IPv4 and IPv6.

5. Change the dns system, delete IPv6 records, through the nginx reverse proxy to achieve IPv6 network access to the IPv4 website.

(in the process of configuration, the gns3 router consumes more cpu and the virtual machine consumes memory, so it is recommended to optimize it. My computer is an i7-8-generation processor with 16G memory.)

At a later stage, the clear and detailed requirements will be gradually realized.
