在Cisco路由器上配置OSPFv3路由协议

     下面我们将以Cisco路由器为例来演示如何配置IPv6下的OSPFv3路由协议，本次实验采用三台Router，router1.ipv6s.com与router2.ipv6s.com运行于骨干区域0，router2.ipv6s.com与router3.ipv6s.com运行于非骨干区域1，每台Router上均起一个Loopback1接口，发布至OSPFv3路由协议中。具体的组网图如下所示：

   

实验组网图与IPv6地址分配

    各设备的接口IPv6地址地址与接口编号请对照下图查看：

     

配置思路与流程说明：

  • 在每台设备上开启IPV6功能:ipv6 unicast-routing
  • 在每台设备上创建OSPFv3进程号100:ipv6 router  ospf   100
  • 为每台设备的OSPFv3进程配置唯一的router-id：router-id  1.1.1.1
              注意：此处的router-id与IPv4中的OSPF一样，仍未32位的IPv4地址形式，但仅标识ID，无IPv4中地址的意义
  • 在相应接口下开启IPv6：ipv6 enable，并配置IPv6地址：ipv6 address  1::1/128
  • 在相应的接口下使能OSPFv3路由协议，并配置该接口需加入的OSPFv3区域号：ipv6 ospf 100 area 0

查看各设备IPv6路由表与OSPFv3邻居状态

所有设备之间的OSPFv3已按照组网图配置完毕，我们可以在router1.ipv6s.com上查看OSPFv3邻居，

并查看IPv6路由表，也能学到router2.ipv6s.com与router3.ipv6s.com上面的loopback接口，

ping  router2.ipv6s.com与router3.ipv6s.com上面的loopback接口ipv6地址，均能正常通讯
