# 路由通告服务：radvd
|
|
|
|
|
|
|
|
|
|
|
|
## 为什么需要 radvd ？
|
|
|
|
|
|
|
|
|
|
|
|
如果你使用主路由方案，宽带也支持 IPv6，且希望家里的设备也都使用 IPv6，那就需要在主路由上部署 radvd 作为路由通告服务，类似 IPv4 的 DHCP 服务，为内网设备分配 IPv6 地址。
|
|
|
|
|
|
|
|
|
|
|
|
## 编译 radvd 镜像
|
|
|
|
|
|
|
|
|
|
|
|
Dockerfile 示例：
|
|
|
|
|
|
|
|
|
|
|
|
```dockerfile title="Dockerfile"
|
|
|
|
|
|
FROM ubuntu:22.04
|
|
|
|
|
|
RUN apt update -y
|
|
|
|
|
|
RUN apt install -y radvd
|
|
|
|
|
|
ENTRYPOINT ["/usr/sbin/radvd", "--config", "/etc/radvd.d/radvd.conf", "--logmethod", "stderr_clean", "--nodaemon"]
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
## 目录结构

|
|
|
|
|

|
|
|
|

```
|

|
|

|
## 准备 radvd.conf
|
|
|
|
|
|
|
|
|
|
|
|
<FileBlock showLineNumbers title="config/radvd.conf" file="home-network/radvd.conf" />
|
|
|
|
|
|
|
|
|
|
|
|
## 准备 daemonset.yaml
|
|
|
|
|
|
|
|
|
|
|
|
<FileBlock showLineNumbers title="config/radvd.yaml" file="home-network/radvd.yaml" />
|
|
|

|
* 使用 initContainer 自动修改内核参数以启用 IPv6 转发和接收路由通告（拨号的网卡通过路由通告接收来自运营商分配的 IPv6 地址）。
