65. 6to4 Tunnel of IPv6 configuration experiment
1, 6to4 Tunnel analysis
The network number 2002: c0a8:6301::/48 of the E0 interface is obtained from:
192.168.99.1 To convert to hexadecimal notation, it is c0a8:6301, and add 20002: to it to get the network number 2002:c0a8:6301::/48. The IP address of the E0 interface can be manually configured or automatically generated via eui-64.
