配置一个双栈网络示例

组网需求

1. 配置R1、R2的接口IP地址
2. 在R1、R2上分别配置OSPFv2和OSPFv3，实现PC1与PC2的双栈访问

组网拓扑

配置思路

1. R1、R2全局和相关接口使能IPv6功能
2. 在PC、R1、R2相应接口配置IPv4和IPv6全球单播地址
3. 在R1、R2上配置OSPFv2，PC1、PC2可以通过IPv4网络通信
4. 在R1、R2上配置OSPFv3，PC1、PC2可以通过IPv6网络通信

配置命令

1. 配置R1、R2全局和接口使能IPv6功能

   • R1配置

     sys
     sys R1
     ipv6
     
     int g0/0/0
       ipv6 enable
     int g0/0/1
       ipv6 enable

• R2配置

  sys
  sys R2
  ipv6
  
  int g0/0/0
    ipv6 enable
  int g0/0/1
    ipv6 enable

2. 在PC1、R1、R2相应接口配置IPv4和IPv6全球单播地址

   • R1配置

     sys
     int g0/0/0
       ip add 10.0.12.1 30
       ipv6 add 2001:db8:1::1/64
     int g0/0/1
       ip add 192.168.1.1 30
       ipv6 add 2001:db8:2::1/64

• R2配置

  sys
  int g0/0/0
    ip add 10.0.12.2 30
    ipv6 add 2001:db8:1::2/64
  int g0/0/1
    ip add 192.168.2.1 30
    ipv6 add 2001:db8:3::1/64

3. 在R1、R2上配置OSPFv2、OSPFv3，使得网络互通

   • R1配置

     sys
     ospf router-id 10.0.1.1
       area 0
         network 10.0.12.0 0.0.0.3
         network 192.168.1.0 0.0.0.3
         
     ospfv3
       router-id 10.0.1.1
       
     int g0/0/0
       ospfv3 1 area 0
     int g0/0/1
       ospfv3 1 area 0

• R2配置

  sys
  ospf router-id 10.0.2.2
    area 0
      network 10.0.12.0 0.0.0.3
      network 192.168.2.0 0.0.0.3
      
  ospfv3
    router-id 10.0.2.2
    
  int g0/0/0
    ospfv3 1 area 0
  int g0/0/1
    ospfv3 1 area 0

查看结果

1. PC1 ping PC2（IPv4网络）

   ping 192.168.2.2
   
   PC>ping 192.168.2.2
