CCNP(BSCI)實驗：手動IPv6 Tunnel（隧道）實驗

手動IPv6 Tunnel（隧道）實驗，適用於IPv4裏跑IPv6
預配置：
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

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
實驗過程：

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：測試隧道

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：調試過程

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

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3::1, timeout is 2 seconds:
