IPv6 实验

一、实验拓扑&实验要求

二、实验过程

1、 配置ipv4公网

r2

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

r3

[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]ip add 23.1.1.2 24
[r3-GigabitEthernet0/0/0]int lo0
[r3-LoopBack0]ip add 3.3.3.3 24
[r3-LoopBack0]int g0/0/1
[r3-GigabitEthernet0/0/1]ip add 34.1.1.1 24

r4

[r4]int g0/0/0
[r4-GigabitEthernet0/0/0]ip add 34.1.1.2 24

2、 配置ipv4私网

r1

[r1]int lo0
[r1-LoopBack0]ip add 192.168.1.1 25
[r1-LoopBack0]int lo1
[r1-LoopBack1]ip add 192.168.1.129 25
[r1-LoopBack1]int g0/0/1
[r1-GigabitEthernet0/0/1]ip add 192.168.0.1 30

r2

[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 192.168.0.2 30

3、ipv4网通

r4上配置缺省

[r4]ip route-static 0.0.0.0 0 34.1.1.1

r2上配置缺省

[r2]ip route-static 0.0.0.0 0 23.1.1.2

此时 r2 可以 ping 通 r4

[r1]ip route-static 0.0.0.0 0.0.0.0 192.168.0.2

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-acl-basic-2000]int g0/0/1
[r2-GigabitEthernet0/0/1]nat outbound 2000

4、r1 r2 上配置ipv6地址

r2

[r2]ipv6
[r2]int lo0
[r2-LoopBack0]ipv6 enable 
[r2-LoopBack0]ipv6 add 2002:1701:0101:0000::1/64

r1

[r1]ipv6
[r1]int g0/0/1
[r1-GigabitEthernet0/0/1]ipv6 enable 
[r1-GigabitEthernet0/0/1]ipv6 address 2002:1701:0101:0001::1/64

r2

[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ipv6 enable 
[r2-GigabitEthernet0/0/0]ipv6 add 2002:1701:0101:0001::2/64

r1

[r1]int lo0
[r1-LoopBack0]ipv6 enable 
[r1-LoopBack0]ipv6 address 2002:1701:0101:0002::1/65
[r1-LoopBack0]int lo1
[r1-LoopBack1]ipv6 enable 
[r1-LoopBack1]ipv6 address 2002:1701:0101:0002:8000::1/65

5、r1 r2 上配置ripng

r1

[r1]ripng 1
[r1-ripng-1]q
[r1]int lo0
[r1-LoopBack0]ripng 1 enable 
[r1-LoopBack0]int lo1
[r1-LoopBack1]ripng 1 enable 
[r1-LoopBack1]int g0/0/1
[r1-GigabitEthernet0/0/1]ripng 1 enable 

r2

[r2]int lo0
[r2-LoopBack0]ripng 1 enable 
[r2-LoopBack0]int g0/0/0
[r2-GigabitEthernet0/0/0]ripng 1 enable

[r1]int g0/0/1
[r1-GigabitEthernet0/0/1]ripng summary-address 2002:1701:0101:0002:: 64

[r2]int t0/0/0
[r2-Tunnel0/0/0]ipv6 enable 
[r2-Tunnel0/0/0]ipv6 address 2002:1701:0101:0003::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

r2向r1做缺省

[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ripng default-route only 

6、r4~r8 上配置ipv6地址

[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]con 
[r5-bgp]confederation id 2
[r5-bgp]router-id 5.5.5.5
[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 
[r5]int lo0
[r5-LoopBack0]ipv6 add 5::5/64

r6

[r6]int lo0
[r6-LoopBack0]ipv6 add 6::6/64

r7

[r7]int lo0
[r7-LoopBack0]ipv6 add 7::7/64

r8

[r8]int lo0
[r8-LoopBack0]ipv6 add 8::8/64

r5上进行建邻（已有r4）

[r5]bgp 64512
[r5-bgp]peer 6::6 as-number 64512
[r5-bgp]peer 6::6 connect-interface lo0 5::5
[r5-bgp]ipv6-family 
[r5-bgp-af-ipv6]peer 6::6 enable 

r6

[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 lo0 6::6
[r6-bgp]peer 7::7 as-number 64512 
[r6-bgp]peer 7::7 connect-interface lo0 6::6
[r6-bgp]ipv6-family  
[r6-bgp-af-ipv6]peer 5::5 enable 
[r6-bgp-af-ipv6]peer 7::7 enable

r7

[r7-bgp]confederation id 2
[r7-bgp]confederation peer-as 64513
[r7-bgp]router-id 7.7.7.7 
[r7-bgp]peer 6::6 as-number 64512
[r7-bgp]peer 6::6 connect-interface lo0 7::7
[r7-bgp]peer 8::8 as-number 64513
[r7-bgp]peer 8::8 connect-interface lo0 7::7
[r7-bgp]peer 8::8 ebgp-max-hop 2
[r7-bgp]ipv6-family 
[r7-bgp-af-ipv6]peer 6::6 enable 
[r7-bgp-af-ipv6]peer 8::8 enable

r8

[r8]bgp 64513
[r8-bgp]router-id 8.8.8.8
[r8-bgp]confederation id 2
[r8-bgp]confederation  peer-as 64512

9、r4~r8路由配置

r4

[r4]int t0/0/0 
[r4-Tunnel0/0/0]ipv6 enable 
[r4-Tunnel0/0/0]ipv6 add 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

r5上先配置空接口（防环）再进行汇总

[r5]ipv6 route-static 2002:2201:0102:8000:: 49 NULL 0
[r5-bgp]ipv6-family 
[r5-bgp-af-ipv6]network 2002:2201:0102:8000:: 49

r4

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

此时r6不优，需在r5上修改下一跳
r5

[r5-bgp]ipv6-family  
[r5-bgp-af-ipv6]peer 6::6 next-hop-local 

r6指定r7为反射器客户端
r6

[r6-bgp-af-ipv6]peer 7::7 reflect-client
