IPv6 comprehensive experiment

One 、 The experimental requirements

R1R2 part ipv4 ipv6 Double stack
R3 Some public networks
Right pure ipv6

Two 、 The experimental steps

1. Build a topology

2. To configure IP Address and loopback address

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 .
according to ipv4 The address calculates ipv6 Then divide the address
R1 Two loops ：
192.168.1.1 25
192.168.1.129 25

R1-R2：
192.168.3.1 24
192.168.3.2 24

R2 Loopback ：192.168.2.1 24

3. First, configure the public network , Make the public network interconnected

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

4. First configure R1 and R2 Between partial LAN and WAN

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

ipv6 part

R1

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:
[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

5. Configure the right public network BGP part

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

AS2：  2002:2201:0102:8000::/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

R6 Loopback ： 2002:2201:0102:8002::1/64
R6-R7： 2002:2201:0102:8003::1/64  2002:2201:0102:8003::2/64

R7 The loopback of ： 2002:2201:0102:8004::1/64
R7-R8： 2002:2201:0102:8005::1/64  2002:2201:0102:8005::2/64

R8 The loopback of ： 2002:2201:0102:8006::1/64
