Preface

How to complete this experiment according to the experimental requirements ？

The experimental requirements ：

1. Two LANs are based on 6to4tunnel Can be up to
2.R1 You can visit R3 Loopback

experimental analysis ：

1. Configure the public network IPV4

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

R2/R4 The default point is to the operator

R2:
 
#
 ip route-static 0.0.0.0 0.0.0.0 23.1.1.2

R4:

 #
ip route-static 0.0.0.0 0.0.0.0 34.1.1.1

At this time, the public network is connected , have access to R2pingR4, Whole IPV4 The public network is connected

 2.R1-R2 To configure IPV4

1. Configure lan ipv4 Address 

R1:

#
interface LoopBack0
 ip address 192.168.1.1 255.255.255.128 
#
interface LoopBack1
 ip address 192.168.1.129 255.255.255.128 
#
interface GigabitEthernet0/0/0
 ip address 192.168.0.1 255.255.255.252 


R2:

#
interface LoopBack0
 ip address 192.168.2.1 255.255.255.0
#
interface GigabitEthernet0/0/0
 ip address 192.168.0.2 255.255.255.252

5.R1 Anti annulus interface

6. At this time, the LAN has been completed , Need to access the public network nat

R2

#

 rule 5 permit source 192.168.0.0 0.0.255.255 
#
interface GigabitEthernet0/0/1
 nat outbound 2000  

here Ipv4 LAN can access the public network

 3. To configure R1-R2 Of IPV6 

because 6to4tunnel , On the left 23.1.1.1 Interface into 2002:1701:0101::/48, On the right 34.1.1.2 Interface into 2002:2101:0102:：/48

 2002:1701:0101::/48

R1:

 When the configuration is complete ipv6 Address and interface declaration ripng after , Optimization summary is needed 
#

#
interface LoopBack0
 ipv6 enable

 ripng 1 enable --- Interface declaration ripng ---- Because multi host 
#

 ipv6 address 2002:1701:101:1::1/64 
 ripng 1 enable
 ripng summary-address 2002:1701:101:2:: 64  ----- Optimize   Summary 


R2:

 ripng 1 enable

#

4.R2 On the configuration 6to4tunnel

R2:

#
interface Tunnel0/0/0
 ipv6 enable 
 ipv6 address 2002:1701:101:3::1/64  
 tunnel-protocol ipv6-ipv4 6to4   --- The goal is ip adopt 6to4 Work out  
 source 23.1.1.1 


#
ipv6 route-static 2002:: 16 Tunnel0/0/0  R2 Need from tunnel Out 


R1:

 Because there are summaries and defaults, ring protection is required  

[R1]ipv6 route-static 2002:1701:101:1:: 64 NULL 0

 At this time, the environment on the left has been completely configured 

5. Configuration right R4-R8 Of IPV6 Address and start IGP
