# IPv6 (Linux systemd)

学校的 DHCPv6 服务器实现比较灵车，Linux桌面或服务器有时候无法获取到 IPv6 地址，如果你使用 systemd-networkd 配置网络，你可以使用以下设置：

注意要让 systemd-networkd 接管网络配置。

创建 `/etc/systemd/network/wan.network`，文件一定要以 .network 结尾。

```
[Match]
Name=`interface`

[Network]
DHCP=yes
IPv6AccpetRA=true

[DHCPv6]
WithoutRA=solicit
DUIDType=link-layer
RapidCommit=false

[IPv6AcceptRA]
Token=eui64
DHCPv6Client=always
```

关键是要把 `RapidCommit=false` 关掉，带上这个标志后学校 DHCPv6 服务器就不会回复 DHCPv6 Solicit 请求。

有时候学校二层里面也不会发 IPv6 RA，所以最好启用 `WithoutRA=solicit` 强制启动 DHCPv6 流程。

Openwrt的客户端并不会带上 RapidCommit，所以没有啥问题。
