about this repogitory

This script receives prefix delegation via DHCPv6-PD from a router on the physical network and advertises RA in the hyper-v virtual network.

Requirement

• The following tasks should be performed in the WSL2 distro.
• Windows host must be connected to a network capable of receiving DHCPv6-PD.
• Enable Windows Subsystem for Linux to use both WSL2 and WSL1.

Install

run install.sh

• Create distro, that name is IPv6.(Alpine 3.14 miniroot)
• Install packages and configuration scripts.
• The distro will be installed in "%USERNAME%\AppData\Local\WSL\IPv6".
• I assume Ubuntu as the execution distro, so some arrangements may be necessary for other distros.

Execute the following command, when the installation is complete.

$ wsl.exe -d ipv6 enable

Check the windows network.

$ powershell.exe ipconfig

If GUA is assigned from upstream, it is successful. After a few seconds, WSL2 will also be assigned IPv6 address.

Register to Task

Now you are ready to configure IPv6.But, after the lease time of DHCPv6-PD expires, connection with the upstream will be disabled. So you can register to the task using installtask.sh script.

You can see your registered task that name is "\WSL\IPv6 Enabler" in the Task Scheduler.
