手动IPv6 Tunnel（隧道）实验，适用于IPv4里跑IPv6 预配置：第一步：配置IP地址

R1(config)#int s2/1 R1(config-if)#ip add 12.0.0.1 255.255.255.0 R1(config-if)#no sh R1(config-if)#int lo0 R1(config-if)#ipv6 add 1::1/64

R3(config)#int lo0 R3(config-if)#ipv6 add 3::1/64 R3(config-if)#int s2/1 R3(config-if)#ip add 23.0.0.3 255.255.255.0 R3(config-if)#no sh

R2(config)#int s2/1 R2(config-if)#ip add 12.0.0.2 255.255.255.0 R2(config-if)#no sh R2(config-if)#int s2/2 R2(config-if)#ip ad 23.0.0.2 255.255.255.0 R2(config-if)#no sh 第二步：配置IPv4路由

R1(config)#router eigrp 123 R1(config-router)#no au R1(config-router)#net 12.0.0.0

R3(config)#router ei 123 R3(config-router)#net 23.0.0.3 R3(config-router)#no au

R2(config)#router ei 123 R2(config-router)#no au R2(config-router)#net 12.0.0.2 R2(config-router)#net 23.0.0.2 R2(config-router)#end 第三步：查看IPv4路由

R1#sh ip rou Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

23.0.0.0/24 is subnetted, 1 subnets D 23.0.0.0 [90/2681856] via 12.0.0.2, 00:00:42, Serial2/1 12.0.0.0/24 is subnetted, 1 subnets C 12.0.0.0 is directly connected, Serial2/1

R2#sh ip rou Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

 23.0.0.0/24 is subnetted, 1 subnets

C 23.0.0.0 is directly connected, Serial2/2 12.0.0.0/24 is subnetted, 1 subnets C 12.0.0.0 is directly connected, Serial2/1

R3#sh ip rou Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2 E1 - OSPF external type 1, E2 - OSPF external type 2 i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2 ia - IS-IS inter area, * - candidate default, U - per-user static route o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

23.0.0.0/24 is subnetted, 1 subnets C 23.0.0.0 is directly connected, Serial2/1 12.0.0.0/24 is subnetted, 1 subnets D 12.0.0.0 [90/2681856] via 23.0.0.2, 00:01:34, Serial2/1 实验过程：

第一步：配置隧道 R1(config)#int tunnel 0 R1(config-if)#tunnel source s2/1 R1(config-if)#tunnel destination 23.0.0.3 R1(config-if)#ipv6 add 13::1/64 R1(config-if)#tunnel mode ipv6ip

R3(config)#int tunnel 0 R3(config-if)#tunnel source s2/1 R3(config-if)#tunnel destination 12.0.0.1 R3(config-if)#ipv add 13::3/64 R3(config-if)#tunnel mode ipv6ip 第二步：测试隧道

R1#ping 13::1

Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 13::1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/3/8 ms 第三步：配置iPv6路由

R1(config)#ipv6 route 3::/64 tunnel 0 R3(config)#ipv6 route 1::/64 tunnel 0 第四步：调试过程

R1#debug ipv6 packet IPv6 unicast packet debugging is on R1#ping 3::1
