IPv6 comprehensive experiment

Subject requirements

1、 Two LANs are based on 6to4tunnel Can be up to

2、R1 You can visit R3 The loopback of

According to the title requirements ：

Ideas

Do the public network and the left first V4 Part of ：

Finish and then pass the default and nat Visit the public network

Do it last V6

Now? R2 Can come out , Want to go R4 You have to build a bridge , Get out yes V6 Headlines , carry V4 Headlines , Source IP yes 23.1.1.1 The goal is IP Is your V6 The address is calculated V4ip, So is 6to4

do 6to4tunnel mouth

Right

up to now , The environment on the left has been set up , Now go to the right ：

34.1.1.2
2002:2201:0102::/48
