Experimental Topology

To configure IP And loopback

First, configure the public network ipv4 Address , Because there's going to be 6to4tunnel Calculate IPV6 Address , So we need to match it first v4 Address .
Configure interface address and loopback address
[R1]int lo0
[R1-LoopBack0]ip ad 192.168.2.1 25
[R1-LoopBack1]int g0/0/1
[R1-GigabitEthernet0/0/1]ip ad 192.168.3.1 30
[R1-GigabitEthernet0/0/1]int lo1
[R1-LoopBack1]ip ad 192.168.2.129 25

[R2]int g0/0/1
[R2-GigabitEthernet0/0/1]ip ad 23.1.1.1 24
[R2]int lo0
[R2-LoopBack0]ip ad 192.168.1.1 24
[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]ip ad 192.168.3.2 30

[R3]int g0/0/0
[R3-GigabitEthernet0/0/0]ip ad 23.1.1.2 24
[R3-GigabitEthernet0/0/0]int g0/0/1
[R3-GigabitEthernet0/0/1]ip ad 34.1.1.1 24
[R3-GigabitEthernet0/0/1]int lo0
[R3-LoopBack0]ip ad 3.3.3.3 24

[R4]int g0/0/0
[R4-GigabitEthernet0/0/0]ip ad 34.1.1.2 24

Configure the public network part

stay R2 R4 Configure one pointing to R3 The default route for
[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

To configure R1 and R2 Between partial LAN and WAN

1.ipv4 part

The default route points to 2
[R1]ip route-static 0.0.0.0 0 192.168.3.2

Static de R1 The loopback of
[R2]ip route-static 192.168.1.1 24 192.168.3.1

do nat address translation , Enable LAN to access the public network
[R2]acl 2000
[R2-acl-basic-2000]rule permit source 192.168.0.0 0.0.255.255
[R2-acl-basic-2000]q
[R2]interface Serial 4/0/1
[R2-Serial4/0/1]nat
[R2-Serial4/0/1]nat ou
[R2-Serial4/0/1]nat outbound 2000

2.ipv6 part

At both ends of the public network , LAN connects to the end of the public network , Use ipv4 The address is calculated as ipv6 The address of
23.1.1.1
2002:1701:0101:0000::/64----2002:1701:0101:FFFF::/64

R1 Loopback 1：2002:1701:0101:0000::1/65
Loopback 2：2002:1701:0101:0000:8000::1/65

R1-R2
2002:1701:0101:1::1/64
2002:1701:0101:1::2/64

R2 Exchange for ：
2002:1701:0101:2::1/64

Use ripng send R1-R2 To communicate with each other
R1：
[R1]ripng 1
[R1-ripng-1]q
[R1]interface LoopBack 0
[R1-LoopBack0]ripng 1 enable
[R1-LoopBack1]ripng 1 enable
[R1-LoopBack1]q
[R1]interface Serial 4/0/1
[R1-Serial4/0/1]ripng 1 enable

R2:
[R2]ripng 1
[R2-ripng-1]q
[R2]interface LoopBack 0
[R2-LoopBack0]ripng 1 enable
[R2-LoopBack0]q
[R2]interface Serial 4/0/0
[R2-Serial4/0/0]ripng 1 enable

Use ipv6 The address leads to the Internet , Use 6to4tunnel
[R2]interface Tunnel 0/0/0
[R2-Tunnel0/0/0]ipv6 en
[R2-Tunnel0/0/0]ipv6 enable
[R2-Tunnel0/0/0]ipv6 address 2002:1701:0101:1::2/64
[R2-Tunnel0/0/0]tunnel-protocol ipv6-ipv4 6to4
[R2-Tunnel0/0/0]source Serial 4/0/1
The goal is not written , Because the goal is to pass ipv4 Calculate the address

Write another static route , go tunnel mouth
[R2]ipv6 route-static 2002:: 16 Tunnel 0/0/0
Just go 2002 All network segments go tunnel mouth

At this point, let R1 I also learned that R2tunnel： static state 、 Reissue 、 stay R2 Write a note on ripng default
Use ripng Send default
[R2]interface Serial 4/0/0
[R2-Serial4/0/0]ripng default-route only

At this point, you can do some optimization , take R1 Two article ipv6 Routes are aggregated into one
[R1]interface Serial 4/0/1
[R1-Serial4/0/1]ripng summary-address 2002:1701:101:: 64

Configure the right public network BGP part

take 34.1.1.2 Calculated as ipv6 Address
2002::2201:0102::/48
Divided into two , Two for each AS

AS1： 2002:2201:0102::/49
2002:2201:0102:0000::/64——2002:2201:0102:7FFF::/49

2002:2201:0102:8000::/64——2002:2201:0102:FFFF::/64

R4 Loopback ：2002:2201:0102:0000::1/64
R4-R5：2002:2201:0102:0001::1/64 2002:2201:0102:0001::2/64

R5 Loopback ：2002:2201:0102:8000::1/64
R5-R6：2002:2201:0102:8001::1/64 2002:2201:0102:8001::2/64
