ipv6-ipv4隧道_ipv4如何升级ipv6

IPv6 over IPv4 GRE隧道（锐捷） 　　拓扑： 　　
　　实验目的 　　R1的Loo0和R5的Loo0接口实现通信 　　操作步骤 　　1.路由器配置各接口IP 　　R1(config)#ipv6 unicast-routing R1(config)#int g0/1 R1(config-if-GigabitEthernet 0/1)#no switchport R1(config-if-GigabitEthernet 0/1)#ipv6 enable R1(config-if-GigabitEthernet 0/1)#ipv6 address 2001:12:1:1::1/64 R1(config-if-GigabitEthernet 0/1)#exit R1(config)#int loo0 R1(config-if-Loopback 0)#ipv6 enable R1(config-if-Loopback 0)#ipv6 address 2001:194:1:10::254/128 R1(config-if-Loopback 0)#exit ​ R2(config)#ipv6 unicast-routing R2(config)#int g0/1 R2(config-if-GigabitEthernet 0/1)#no switchport R2(config-if-GigabitEthernet 0/1)#ipv6 enable R2(config-if-GigabitEthernet 0/1)#ipv6 address 2001:12:1:1::254/64 R2(config-if-GigabitEthernet 0/1)#exit R2(config)#int g0/0 R2(config-if-GigabitEthernet 0/0)#no switchport R2(config-if-GigabitEthernet 0/0)#ip add 23.1.1.2 255.255.255.0 R2(config-if-GigabitEthernet 0/0)#exit ​ R3(config)#int g0/0 R3(config-if-GigabitEthernet 0/0)#no switchport R3(config-if-GigabitEthernet 0/0)#ip add 23.1.1.3 255.255.255.0 R3(config-if-GigabitEthernet 0/0)#exit R3(config)#int g0/1 R3(config-if-GigabitEthernet 0/1)#no switchport R3(config-if-GigabitEthernet 0/1)#ip add 34.1.1.3 255.255.255.0 R3(config-if-GigabitEthernet 0/1)#exit ​ R4(config)#int g0/1 R4(config-if-GigabitEthernet 0/1)#no switchport R4(config-if-GigabitEthernet 0/1)#ip add 34.1.1.4 255.255.255.0 R4(config-if-GigabitEthernet 0/1)#exit R4(config)#ipv6 unicast-routing R4(config)#int g0/0 R4(config-if-GigabitEthernet 0/0)#ipv6 add   R4(config-if-GigabitEthernet 0/0)#no switchport R4(config-if-GigabitEthernet 0/0)#ipv6 enable R4(config-if-GigabitEthernet 0/0)#ipv6 address 2001:45:1:1::254/64 R4(config-if-GigabitEthernet 0/0)#exit ​ R5(config)#ipv6 unicast-routing R5(config)#int g0/0 R5(config-if-GigabitEthernet 0/0)#no switchport R5(config-if-GigabitEthernet 0/0)#ipv6 enable R5(config-if-GigabitEthernet 0/0)#ipv6 address 2001:45:1:1::1/64 R5(config-if-GigabitEthernet 0/0)#exit R5(config)#int loo0 R5(config-if-Loopback 0)#ipv6 enable R5(config-if-Loopback 0)#ipv6 address 2001:195:1:10::254/128 R5(config-if-Loopback 0)#exit 　　2.R1和R2；R4和R5之间启用OSPFv3 　　R1(config)#ipv6 router ospf 1 R1(config-router)#router-id 1.1.1.1 Change router-id and update OSPFv3 process!
