IPv6 transition technology-6to4 manual tunnel configuration experiment -- Kuige of Shangwen network

We talked about it before IPv6 What are the transition technologies , This time, let's see how to configure , As for the dual stack technology, we will not analyze it separately , This article mainly takes Huawei equipment as the starting point to make a 6to4 Manual tunnel experiment .

One 、 The topology

Two 、 The goal of the experiment

The blue part is IPv4 part , To configure IPv6 Manual tunneling 1::1 and 5::5 You can go through IPv4 Networks communicate with each other

3、 ... and 、 The experimental steps

1： Configure as shown in the figure IP Address
2： To configure R2、R3、R4 Between ospf
With R2 For example ：

[R2]ospf 1 
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network  23.1.1.0 0.0.0.255
[R2-ospf-1-area-0.0.0.0]network  2.2.2.2 0.0.0.0

3： To configure R1 and R2、R4 and R5 Between ospfv3

[R1]ospfv3  1 
[R1-ospfv3-1]router-id 1.1.1.1
[R1-ospfv3-1]area 0 
[R1]int g0/0/0
[R1-GigabitEthernet0/0/0]ospfv3 1 area 0
[R1]int lo0
[R1-LoopBack0]ospfv3 1 area 0
[R2]ospfv3 1 
[R2-ospfv3-1]router-id 2.2.2.2
[R2-ospfv3-1]area  0
[R2]interface  GigabitEthernet 0/0/0
[R2-GigabitEthernet0/0/0]ospfv3 1 area 0

R4 and R5 Same configuration

4： To configure R2 and R4 Between 6over4 Tunnel

[R2]interface  Tunnel  0/0/0	   // Create a virtual tunnel interface 
[R2-Tunnel0/0/0]tunnel-protocol ipv6-ipv4   // Choose tunnel encapsulation protocol （GRE It's fine too ）
[R2-Tunnel0/0/0]source  2.2.2.2    // Configure the tunnel source address 
[R2-Tunnel0/0/0]destination 4.4.4.4   // Configure the tunnel destination address （ The two addresses must be interconnected ）
[R2-Tunnel0/0/0]ipv6  enable  	// Open tunnel interface IPv6 function 
[R2-Tunnel0/0/0]ipv6  address  2001:24::2 64  // Configure the tunnel IPv6 Address , For subsequent protocol use 
[R4]interface  Tunnel 0/0/0
[R4-Tunnel0/0/0]tunnel-protocol ipv6-ipv4   // The tunnel packages on both sides must be consistent 
[R4-Tunnel0/0/0]source  4.4.4.4
[R4-Tunnel0/0/0]destination 2.2.2.2
[R4-Tunnel0/0/0]ipv6  enable  
[R4-Tunnel0/0/0]ipv6  address  2001:24::4 64
 

5： Configure through tunnel interface ospfv3 Connect the networks on both sides

[R2]interface  Tunnel  0/0/0
[R2-Tunnel0/0/0]ospfv3 1 area 0
[R4]interface  Tunnel  0/0/0
[R4-Tunnel0/0/0]ospfv3 1 area 0
 

At present, passing through the tunnel is equivalent to R2 and R4 Directly connected , So use tunnel configuration ospfv3 And the networks on both sides are also configured ospfv3 agreement , So you can communicate directly . If one side of the network is ospfv3 On the other hand isis, The intermediate tunnel interface can choose any protocol configuration and join the route introduction .
Join a group to talk about technology , If you have any questions, you can share them directly QQ Group ：316317765, You can also pay attention to the next official account. , More information will be released later .
