IPv6 experiment

1、 Two LANs are based on 6to4tunnel Can be up to
2、R1 You can visit R3 The loopback of

One 、 To configure ipv4, Connect the public network first and then the private network

Two 、ipv6 To configure ripng

23.1.1.1 Conversion to ipv6 The address is 2002：1701：0101：：/48 On this basis, the subnet is divided

[r1]ipv6 
[r1]int l0
[r1-LoopBack0]ipv6 enable 
[r1-LoopBack0]ipv6 add 2002:1701:0101::1 65
[r1-LoopBack0]int l1
[r1-LoopBack1]ipv6 enable 
[r1-LoopBack1]ipv6 add 2002:1701:0101::8000::1 65
[r1-LoopBack1]int g0/0/0
[r1-GigabitEthernet0/0/0]ipv6 enable 
[r1-GigabitEthernet0/0/0]ipv6 add 2002:1701:0101:0001::1 64


[r2]ipv6
[r2]int g0/0/1
[r2-GigabitEthernet0/0/1]ipv6 enable 
[r2-GigabitEthernet0/0/1]ipv6 add 2002:1701:0101:0001::2 64
[r2-GigabitEthernet0/0/1]int l0
[r2-LoopBack0]ipv6 enable 
[r2-LoopBack0]ipv6 add 2002:1701:0101:0002::1 64

rise r1 and r2 Of ripng

[r1]ripng 1
[r1-ripng-1]int l0
[r1-LoopBack0]ripng 1 enable 
[r1-LoopBack0]int l1
[r1-LoopBack1]ripng 1 enable 
[r1-LoopBack1]int g0/0/0
[r1-GigabitEthernet0/0/0]ripng 1 enable 


[r2]ripng 1
[r2-ripng-1]int l0
[r2-LoopBack0]ripng 1 enable 
[r2-LoopBack0]int g0/0/1
[r2-GigabitEthernet0/0/1]ripng 1 enable

Let's do it here ip Optimize the address , take r1 and r2 The loopback of

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]ripng summary-address 2002:1701:0101:0000:: 64

here r1 and r2 Learned each other's loopback
Internal dependence 6to4tunnel get out

[r2]int t0/0/0
[r2-Tunnel0/0/0]ipv6 enable 
[r2-Tunnel0/0/0]ipv6 add 2002:1701:0101:0003::1 64
[r2-Tunnel0/0/0]tunnel-protocol ipv6-ipv4 6to4 
[r2-Tunnel0/0/0]source g0/0/0

meanwhile r2 There must be a route on

[r2]ipv6 route-static 2002:: 16 t0/0/0

Now is 1 There is no route to the outside , Give Way 2 to 1 Send a default

[r2]int g0/0/1
[r2-GigabitEthernet0/0/1]ripng default-route only 

3、 ... and 、ipv6 Internal subnet
34.1.1.2 Conversion to ipv6 by 2002：2201：0110：：/ 48, On this basis, the subnet is divided

[r4]ipv6

[r5-LoopBack0]int g0/0/0
[r5-GigabitEthernet0/0/0]ipv6 enable 
[r5-GigabitEthernet0/0/0]ipv6 add 2002:2201:0102:8001::2 64

[r6-GigabitEthernet0/0/0]ipv6 enable 
[r6-GigabitEthernet0/0/0]ipv6 add 2002:2201:0102:8003::1 64

[r7]ipv6 
[r7]int g0/0/1
[r7-GigabitEthernet0/0/1]ipv6 enable
