IPV6综合实验

题目要求

1、两个局域网基于6to4tunnel可达

2、R1可以访问R3的环回

根据题目要求：

思路

先做公网和左边V4的部分：

做完然后通过缺省和nat访问公网

最后做V6

[r2]int g0/0/1
[r2-GigabitEthernet0/0/1]ip ad	
[r2-GigabitEthernet0/0/1]ip address 23.1.1.1 24

[r4]ip route-static 0.0.0.0 0 34.1.1.1 
[r4]


[r1]int l0

[r1-LoopBack0]int l1

R1汇总+空接口 R2发布缺省

[r1]int g0/0/1
[r1-GigabitEthernet0/0/1]rip summary-address 192.168.1.0 255.255.255.0
[r1-GigabitEthernet0/0/1]q

[r1]ip route-static 192.168.1.0 24 NULL 0
[r1]
[r2]rip 1
[r2-rip-1]default-route originate 

上网的NAT

[r2]acl 2000
[r2-acl-basic-2000]rule permit source 192.168.0.0 0.0.255.255
[r2-acl-basic-2000]int g0/0/1
[r2-GigabitEthernet0/0/1]nat outbound 2000

R1可以上网了，现在V4部分全部弄好了，去弄V6部分

1、先确定IP

23.1.1.1
2002:1701:0101::/48
2002:1701:0101:0000::/64   ~2002:1701:0101:FFFF::/64 

2002:1701:0101:0000::/64
2002:1701:0101:0000:0000 0000 0000 0000::/65      
2002:1701:0101:0000:1000 0000 0000 0000::/65     
2002:1701:0101:0000:8000:：/65   

2002:1701:0101:0000::/64
给到1的两个环回第一个网段
1的1个环回2002:1701:101::/65
1的2个环回2002:1701:101:0:8000:：/65

一连二第二个网段
2002:1701:0101:1::1 64
2002:1701:0101:1::2 64

给到2的环回用第三个网段
2002:1701:0101:2::1 64

左边IPV6

[r1]ipv6
[r1]int l0  
[r1-LoopBack0]ipv6 enable 
[r1-LoopBack0]ipv6 address 2002:1701:101::1 65
[r1-LoopBack0]int l1
[r1-LoopBack1]ipv6 enable 
[r1-LoopBack1]ipv6 address 2002:1701:101:0:8000::1 65

[r1-LoopBack1]int g0/0/1
[r1-GigabitEthernet0/0/1]ipv6 enable 
[r1-GigabitEthernet0/0/1]ipv6 address 2002:1701:0101:1::1 64


[r2]ipv6
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ipv6 enable 
[r2-GigabitEthernet0/0/0]ipv6 address 2002:1701:0101:1::2 64

[r2-GigabitEthernet0/0/0]int l0
[r2-LoopBack0]ipv6 enable
[r2-LoopBack0]ipv6 address 2002:1701:0101:2::1 64

R1R2之间的RIPNG

[r1]ripng 1
[r1-ripng-1]int l0
[r1-LoopBack0]ripng 1 enable 
[r1-LoopBack0]int l1	
[r1-LoopBack1]ripng 1 enable 
[r1-LoopBack1]int g0/0/1
[r1-GigabitEthernet0/0/1]ripng 1 enable 

[r2]ripng 1 
[r2-ripng-1]int l0
[r2-LoopBack0]ripng 1 enable 
[r2-LoopBack0]int g0/0/0
[r2-GigabitEthernet0/0/0]ripng 1 enable 

R1R2优化：

R1环回汇总和空接口
[r1-GigabitEthernet0/0/1]ripng summary-address 2002:1701:0101:0000:: 64
[r1]ipv6 route-static 2002:1701:0101:0000:: 64 NULL 0


R2发布缺省：在边界路由器连接内网的接口上
[r2-GigabitEthernet0/0/0]ripng default-route only 

现在R2能出的来，要去R4就得搭桥，出去是V6报头，携带V4报头，源IP是23.1.1.1 目标IP是你的V6地址算出来的V4ip，所以就是6to4

做6to4tunnel口

[r2]int Tunnel 0/0/0
[r2-Tunnel0/0/0]ipv6  enable 
[r2-Tunnel0/0/0]ipv6 address 2002:1701:0101:3::1 64

[r2-Tunnel0/0/0]tunnel-protocol ipv6-ipv4 6to4 
[r2-Tunnel0/0/0]source 23.1.1.1
[r2-Tunnel0/0/0]q

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

到目前为止，左边的环境已经全部搭建起来了，现在去做右边的：

34.1.1.2
2002:2201:0102::/48
右边是AS划分，有个2个AS
2002:2201:0102::/49         AS1
2002:2201:0102:8000::/49	AS2


然后向内划分
2002:2201:0102::/64  ~2002:2201:0102:7fff::/64      AS1
2002:2201:0102:8000::/64 ~2002:2201:0102:ffff::/64  AS2

配完之后开始建邻，查看邻居表

查看R5路由表齐了之后开始起BGP

R4R5之间EBGP

[r4]bgp 1
[r4-bgp]router-id 4.4.4.4
[r4-bgp]peer 2002:2201:102:1::2 as-number 2	
[r4-bgp]ipv6-family 
[r4-bgp-af-ipv6]peer 2002:2201:102:1::2 enable 


[r5]bgp 64512
[r5-bgp]router-id 5.5.5.5
[r5-bgp]confederation id 2
[r5-bgp]peer 2002:2201:102:1::1 as-number 1
[r5-bgp]ipv6-family 
[r5-bgp-af-ipv6]peer 2002:2201:102:1::1 enable 

但是这样配置太麻烦了，这就要引出本地站点，多数组的概念，一个环回可以有多个V6地址
[r5-LoopBack0]ipv6 address 5::5 64
[r6-LoopBack0]ipv6 address 6::6 64
[r7-LoopBack0]ipv6 address 7::7 64
[r8-LoopBack0]ipv6 address 8::8 64

再来
[r5]bgp 64512
[r5-bgp]peer 6::6 as-number 64512 
[r5-bgp]peer 6::6 connect-interface LoopBack 0 5::5
[r5-bgp]ipv6-family 
[r5-bgp-af-ipv6]peer 6::6 enable 

[r6]bgp 64512

[r6-bgp]router-id 6.6.6.6
[r6-bgp]confederation id 2
[r6-bgp]peer 5::5 as-number 64512
[r6-bgp]peer 5::5 connect-interface LoopBack 0 6::6
[r6-bgp]peer 7::7 as-number 64512
[r6-bgp]peer 7::7 connect-interface LoopBack 0 6::6
[r6-bgp]ipv6-family 
[r6-bgp-af-ipv6]peer 5::5 enable 
[r6-bgp-af-ipv6]peer 7::7 enable 
[r6-bgp-af-ipv6]

[r7]bgp 64512

[r7-bgp-af-ipv6]peer 6::6 enable 	
[r7-bgp-af-ipv6]peer 8::8 enable 

[r8]bgp 64513
[r8-bgp]router-id 8.8.8.8
[r8-bgp]confederation id 2
[r8-bgp]confederation peer-as 64512
[r8-bgp]peer 7::7 as-number 64512
[r8-bgp]peer 7::7 connect-interface LoopBack 0 8::8
[r8-bgp]peer 7::7 ebgp-max-hop 2
[r8-bgp]ipv6-family 	
[r8-bgp-af-ipv6]peer 7::7 enable 

现在我们来思考，还缺哪些路由，R4向左缺个6to4tunnel，和一条道2002:: /16的缺省

R4向右边，需要学到整个AS2，而他学AS2只能靠BGP，所以4需要右边有个BGP导过来

5678内部是齐的，只需要一条到2002:: /16的，指向4

我们先来做4

[r4]int Tunnel 0/0/0
[r4-Tunnel0/0/0]ipv6 enable 
[r4-Tunnel0/0/0]ipv6 address 2002:2201:0102:2::1 64
[r4-Tunnel0/0/0]tunnel-protocol ipv6-ipv4 6to4 
[r4-Tunnel0/0/0]source 34.1.1.2
[r4]ipv6 route-static 2002:: 16 Tunnel 0/0/0

汇总5678 2002:2201:0102:8000:: 49 NULL 0

[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

R4宣告缺省

[r4]bgp 1
[r4-bgp]ipv6-family 
[r4-bgp-af-ipv6]network 2002:: 16

路由传给5 EBGP关系，所以优，5传给6不优，因为IBGP关系，所以更改下一跳
[r5]bgp 64512
[r5-bgp]ipv6-family 
[r5-bgp-af-ipv6]peer 6::6 next-hop-local 

6优了会传给7吗？不会，因为IBGP水平分割，调一个反射器
[r6]bgp 64512
[r6-bgp]ipv6-family 
[r6-bgp-af-ipv6]peer 7::7 reflect-client 

测试：

实验完成！
