IPV6实验

实验题目：IPV6实验

实验目的：

1. 两个局域网基于6to4tunnel可达
2. R1可以访问R3的环回

实验拓扑：

 

实验内容：

1.ip地址的规划

先规划ipv4地址：

公网部分：23.1.1.0/24  34.1.10/24

Ipv4私网部分：r1:环回1:192.168.1.1/25  环回2：92.168.1.129/25 网段：192.168.0.0/30

R2环回：192.168.2.1/24

再规划ipv6部分：

因为要用到6to4 tunnel 所以 用r2的g0/0/1和r4的g0/0/0的ipv4地址来规划两个ipv6区域的ipv6地址

V4/v6区域：

R2的g0/0/1口ipv4地址：23.1.1.1     2002:1701:0101:0000::/64

v6区域：r4的g0/0/0口的ip地址：34.1.1.2   2002:2201:0102::/48

2002:2201:0102::0/49   as1

2002:2201:0102::0/64-2002:2201:0102:7ffff::/64

2002:2201:0102:8000::/49   as2

2002:2201:0102:8000::/64-2002:2201:0102:ffff::/64

2.ipv4公网部分的配置

[r2-GigabitEthernet0/0/1]ip add 23.1.1.1 24

[r3-LoopBack0]ip add 3.3.3.3 24

[r3-GigabitEthernet0/0/0]ip add 23.1.1.2 24

[r3-GigabitEthernet0/0/1]ip add 34.1.1.1 24

[r4-GigabitEthernet0/0/0]ip add 34.1.1.2 24

R3作为isp

所以r2和r4各配置一个缺省指向r3

[r2]ip route-static 0.0.0.0 0 23.1.1.2

[r4]ip route-static 0.0.0.0 0 34.1.1.1

此时公网已通

 

 

3.配置ipv4v6双栈区域的ipv4

让此区域能够访问公网

[r1-LoopBack0]ip add 192.168.1.1 25

[r1-LoopBack1]ip add 192.168.1.129 25

[r1-GigabitEthernet0/0/0]ip add 192.168.0.1 30

[r2-GigabitEthernet0/0/0]ip add 192.168.0.2 30

[r2-LoopBack0]ip add 192.168.2.1 24

配置静态路由 让私网部分通 然后再在r2的出口配置NAT 让私网能够访问公网

[r1]ip route-static 0.0.0.0 0 192.168.0.2  r1一条缺省指向r2

[r2]ip route-static 192.168.1.0 24 192.168.0.1  

[r2]acl 2000  

[r2-acl-basic-2000]rule permit source 192.168.0.0 0.0.255.255

[r2-GigabitEthernet0/0/1]nat outbound 2000

此时：r1已经可以访问r3的环回

4.ipv4v6双栈ipv6的配置

[r1]ipv6

[r1-LoopBack0]ipv6 enable

[r1-LoopBack0]ipv6 add 2002:1701:0101:0000::1 65

[r1-LoopBack1]ipv6 enable

[r1-LoopBack1]ipv6 add 2002:1701:0101:0000:8000::1 65

[r1-GigabitEthernet0/0/0]ipv6 enable

[r1-GigabitEthernet0/0/0]ipv6 add 2002:1701:0101:1::1 64

[r2]ipv6

[r2-GigabitEthernet0/0/0]ipv6 enable

[r2-GigabitEthernet0/0/0]ipv6 add 2002:1701:0101:1::2 64

[r2-LoopBack0]ipv6 enable

[r2-LoopBack0]ipv6 add 2002:1701:0101:2::1 64

启ripng：

[r1]ripng 1

[r1-LoopBack0]ripng 1 enable

[r1-LoopBack1]ripng 1 enable

[r1-GigabitEthernet0/0/0]ripng 1 enable

[r2]ripng 1

[r2-LoopBack0]ripng 1 enable

[r2-GigabitEthernet0/0/0]ripng 1 enable

优化汇总：[r1-GigabitEthernet0/0/0]ripng summary-address 2002:1701:0101:0000:: 64

此时：ripng的路由都只有一条

 

 

5.ipv4v6双栈的6to4tunnel

[r2]interface Tunnel 0/0/0

[r2-Tunnel0/0/0]ipv6 enable

[r2-Tunnel0/0/0]ipv6 add 2002:1701:0101:3::1 64  

[r2-Tunnel0/0/0]tunnel-protocol ipv6-ipv4

[r2-Tunnel0/0/0]source 23.1.1.1

           

[r2]ipv6 route-static 2002:: 16 Tunnel 0/0/0

[r2-GigabitEthernet0/0/0]ripng default-route only  

此时r1上已经有一条缺省

9.AS1处的tunnel

[r4]interface t

[r4]interface Tunnel 0/0/0

10.AS2的宣告  as1要学到as2的路由

我们用空接口来宣告整个as2的路由

[r5]ipv6 route-static 2002:2201:0102:8000:: 49 NULL 0

[r5]bgp 64512                                            

[r5-bgp]ipv6-family

[r5-bgp-af-ipv6]network 2002:2201:0102:8000:: 49

11.AS2学到右边所有的路由

所以让r4宣告2002:: 16 网段

[r4]bgp 1

[r4-bgp]ipv6

[r4-bgp-af-ipv6]net

[r4-bgp-af-ipv6]network 2002:: 16
