HCIP实验（10）

【1】配置IPV4

1.配置IPV4的公网IP、环回和路由

[r2]int g0/0/1
[r2-GigabitEthernet0/0/1]ip  add 23.1.1.1 24
[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]ip add 23.1.1.2 24
[r3]int g0/0/1
[r3-GigabitEthernet0/0/1]ip add 34.1.1.1 24
[r3]int lo0
[r3-LoopBack0]ip add 3.3.3.3 24
[r4]int g0/0/0
[r4-GigabitEthernet0/0/0]ip add 34.1.1.2 24

（测试）

配置V4公网的路由

[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

（测试）

2.配置IPV4的私网IP、环回和路由

[r1]int lo0
[r1-LoopBack0]ip add 192.168.1.1 25
[r1]int lo1
[r1-LoopBack1]ip add 192.168.1.129 25
[r1]int g0/0/1
[r1-GigabitEthernet0/0/1]ip add 192.168.0.1 30
[r2]int lo0
[r2-LoopBack0]ip add 192.168.2.1 24
[r2]int g0/0/0
[r2-GigabitEthernet0/0/0]ip add 192.168.0.2 30

配置私网路由

[r1]ip route-static 0.0.0.0 0 192.168.0.2
[r2]ip route-static 192.168.1.0 24 192.168.0.1

3.R2上有出去的路由，在R2的g0/0/1端口做一个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

（测试）

【2】配置IPV6

1.（定IP）用IPV4地址换算IPV6地址

23.1.1.1
2002:1701:0101:0000::/64 -- 2002:1701:0101:FFFF::/64

34.1.1.2
2002:2201:0102::/48
2002:2201:0102::/49    AS1
2002:2201:0102::/64   ---   2002:2201:0102:7FFF::/64
2002:2201:0102:8000::/49    AS2
2002:2201:0102:8000::/64   ---   2002:2201:0102:FFFF::/64

2.配置R1、R2的IPV6的内部地址和环回

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

在内部使用RIPNG形成通路
