在Cisco路由器上配置IPv6 Over IPv4 手工隧道

     下面我们将以Cisco路由器为例来演示如何在Cisco路由器上配置IPv6 Over IPv4 手工隧道，本次实验采用三台Router，router1.ipv6s.com、router2.ipv6s.com、router3.ipv6s.com均通过IPv4网络互联，运行OSPF协议模拟IPv4 Internet。router1.ipv6s.com、router3.ipv6s.com这二台路由器均为双栈路由器。router1.ipv6s.com、router3.ipv6s.com通过router2.ipv6s.com建立6Over4的手工隧道，连接二边的IPv6网络。实验中我们未在二边的IPv6网络放置PC机，因此各在二台设备上建立一个loopback接口，与隧道一起运行OSPFv3路由协议，验证将二边的IPv6网络通过6Over4 手工隧道进行互联互通。具体的组网图如下所示：

   

实验组网图与IPv4、IPv6地址分配

    各设备的接口IPv4、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：

  • 在每台设备上配置IPv4地址并通过ospf路由协议将IPv4网络连通
  • 在第一与第三台路由器上开启IPV6功能:ipv6 unicast-routing
  • 在每台设备上创建OSPFv3进程与loopback接口地址并使能OSPFv3路由协议
  • 建立隧道，并配置隧道模式为6over4手工隧道：tunnel mode ipv6ip
  • 配置6over4手工隧道的源IPv4地址与隧道对端的目的IPv4地址tunnel source    tunnel  destination
  • 配置隧道的IPv6地址并使能OSPFv3路由协议，将二边的IPv6网络通过隧道连通

查看各设备OSPF与OSPFv3邻居、IPv6路由表

所有设备之间的IPv4、IPv6路由协议已按照组网图配置完毕，我们可以在router1.ipv6s.com上查看OSPF、OSPFv3的邻居

并查看IPv6路由表，隧道接口的IPv6地址信息。

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