Wireless Network IPv6 Network Construction

IPv6 is an inevitable trend of Internet upgrading and evolution, an important direction of network technology innovation, and the basic support for building a strong network country. The unit connected to the IPv6 of the education network last year, and built an IPV6 network on the basis of wired and wireless networks. It can be used under the pure IPv6 protocol, and most of them are used by IPv4+IPv6. Tens of thousands of IPv6 user addresses are connected to the Internet, and the IPv6 egress bandwidth can reach more than 5 Gbps. The homepage of the unit has also opened IPv6, but through 6TO4 conversion, the following describes the construction process.

1. The access of IPv6 is to add an IPv6 address to the IPv4 interface of the original egress device. In the past two years, the IPv6 export of the education network was opened first, and the mobile IPv6 export of the student dormitory was newly added this year. At present, the wireless network and the IPv6 network of the student dormitory use the IPv6 address of the mobile company, which starts with 2409:8750, and the export uses the mobile IPv6 export.

2. Configure DHCP for IPv6 on the core network switch. IPv6 is divided into stateful and stateless address acquisition because the stateless one cannot automatically obtain the DNS server address, and users have to configure the DNS server address by themselves, which is difficult for ordinary users. The unit obtains the IPv6 address in a stateful manner, and a DHCP server needs to be configured. Because the wireless network is flat, DHCP is established on the core switch.

3. Configure the wireless network VLAN on the core switch. After using the IPv6 nd prefix 2409:8750:XXXX: 712::/64 no-autoconfig command, the wireless network of the mobile phone cannot automatically obtain an IPv6 address, because some websites on the Internet do not support IPv6, and there is basically no way in the network settings of the mobile phone Cancel the IPv6 protocol. When mobile phone wireless network users use the network, because some websites do not support IPv6, they always feel that there is a problem with the network. I can only use this command to prevent the mobile phone wireless network from automatically obtaining an IPv6 address. On the computer, you can not select Internet Protocol Version 6 (TCP/IPv6) in the Ethernet properties and only use the IPv4 protocol. If you want to use IPv6, you can only select IPv6. Most computers default to IPv4+IPv6 protocol, and the default is IPv6 priority. Users with strong hands-on ability can modify the computer to IPv4 first, open the registry and find DisabledComponents, if not, right-click to create a new (DWORD 32-bit) data value, enter 20 (ten For the hexadecimal, enter 32 for decimal).

4. Release IPv6 on the AC

Regardless of whether IPv4 is authenticated or not, IPv6 packets are fully released. Use the command address-bind ipv6-mode lose, and there are three optional parameters. IPv6 packets after IPv4 authentication can pass: compatible; whether IPv4 is authenticated or not, IPv6 packets can pass: loose; all IPv6 packets cannot pass (default): strict.
