组网需求
- 某公司通过部署OSPFv2实现IPv4网络的互联互通
- 为了保证业务的发展，同时部署IPv6网络，部署OSPFV3实现IPv6网络的互联互通
- 所有路由器运行OSPFv2和OSPFv3路由协议，整个自治系统分成3个区域
- 配置完成后，每台路由器都应该学到AS内所有网段的IPv4路由和IPv6路由
组网拓扑
配置思路
- 先配置IPv4网络
- 配置各个路由器基本功能以及接口IP地址
- 配置OSPFv2路由协议，Router-ID、区域号、宣告路由
- 再配置IPv6网络
- 配置全局使能IPv6功能，各个路由器接口配置IPv6链路本地地址和IPv6全球单播地址
- 配置OSPFv3路由协议，Router-ID
- 各个接口使能IPv6功能，配置OSPFv3进程和区域
配置命令
