试验背景： 公司构建了２个 IPV6 的网络，但是这两个网络不在同一个地域范围内，如果要想通信，必须要跨越 IPV4 的网络，为了达到通信的目的，决定采用隧道技术。
  试验目的： 1 、采用 GRE 隧道技术来实现；
            2 、实现 PC1 能够和 PC2 之间 PING 通；
            3 、 IPV6 路由的实现采用 IPV6 RIP 实现；
  试验拓扑：



1. 配置路由器端口的 ip 地址
 
Router#
Router#conf t
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)#no ip domain lookup
Router(config)#hostname aaa
aaa(config)#interface f0/0
aaa(config-if)#no switchport
aaa(config-if)#ip add 192.168.1.1 255.255.255.0
aaa(config-if)#no shut
aaa(config-if)#exit
aaa(config)#interface loopback 1
aaa(config-if)#ipv6 address 2000::1/64
aaa(config-if)#exit
 
Router#conf t
Router(config)#no ip domain lookup
Router(config)#hostname bb
bb(config)#interface f0/0
bb(config-if)#no switchport
bb(config-if)#ip add 192.168.1.2 255.255.255.0
bb(config-if)#no shut
bb(config-if)#exit
bb(config)#interface f0/1
bb(config-if)#no switchport
bb(config-if)#ip add 172.16.1.1 255.255.255.0
bb(config-if)#no shut
bb(config-if)#exit
 
Router#conf t
Router(config)#no ip domain lookup
Router(config)#hostname ccc
ccc(config)#interface f0/0
ccc(config-if)#no switchport
ccc(config-if)#ip add 172.16.1.2 255.255.255.0
ccc(config-if)#no shut
ccc(config-if)#exit
ccc(config)#interface loopback 1
ccc(config-if)#ipv6 add 2001::1/64
ccc(config-if)#exit
 
2. 配置 ipv4 的动态路由
 
aaa(config)#router rip
aaa(config-router)#version 2
aaa(config-router)#no auto-summary
aaa(config-router)#network 192.168.1.0
aaa(config-router)#exit
 
bb(config)#router rip
bb(config-router)#version 2
bb(config-router)#no auto-summary
bb(config-router)#network 192.168.1.0
bb(config-router)#network 172.16.1.0
bb(config-router)#exit
 
ccc(config)#router rip
ccc(config-router)#version 2
ccc(config-router)#no auto-summary
ccc(config-router)#network 172.16.1.0
ccc(config-router)#exit
 
3. 查看路由表
 
aaa#show 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
 
     172.16.0.0/24 is subnetted, 1 subnets
R       172.16.1.0 [120/1] via 192.168.1.2, 00:00:01, FastEthernet0/0
C    192.168.1.0/24 is directly connected, FastEthernet0/0
 
bb#show 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
 
     172.16.0.0/24 is subnetted, 1 subnets
C       172.16.1.0 is directly connected, FastEthernet0/1
C    192.168.1.0/24 is directly connected, FastEthernet0/0
 
ccc#show ip rou

       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

     172.16.0.0/24 is subnetted, 1 subnets
C       172.16.1.0 is directly connected, FastEthernet0/0
R    192.168.1.0/24 [120/1] via 172.16.1.1, 00:00:01, FastEthernet0/0
 
4. 给路由器做隧道
 
aaa#conf t
aaa(config)#interface tunnel 1
aaa(config-if)#ipv6 address 2002::1/64
aaa(config-if)#tunnel source 192.168.1.1
aaa(config-if)#tunnel destination 172.16.1.2
aaa(config-if)#exit
 
ccc(config)#interface tunnel 1
ccc(config-if)#ipv6 address 2003::1/64
ccc(config-if)#tunnel source 172.16.1.2
ccc(config-if)#tunnel destination 192.168.1.1
 
5. 在路由器上配置 ipv6 并应用到接口
 
aaa(config)#ipv6 unicast-routing
aaa(config)#ipv6 router rip wang
aaa(config-rtr)#exit
aaa(config)#interface tunnel 1
aaa(config-if)#ipv6 rip wang enable
aaa(config-if)#exit
aaa(config)#interface loopback 1
aaa(config-if)#ipv6 rip wang enable
 
ccc(config)#ipv6 unicast-routing
ccc(config)#ipv6 router rip wang
ccc(config)#interface tunnel 1
ccc(config-if)#ipv6 rip wang enable
ccc(config)#interface loopback 1
ccc(config-if)#ipv6 rip wang enable
ccc(config-if)#exit
 
6. 查看 ipv6 的路由表

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2001::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 276/492/668 ms
 
ccc#ping 2000::1
 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2000::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 532/610/740 ms
