Ip address 1.1.1.254 255.255.255.0 Ip cef Tunnel adapter isatap.{0DB7233C-89B7-49DB-A8C0-D1AA005F4E6A}: Network 2.2.2.2 0.0.0.0 area 0 Multicast !! Match the exit of the packet 2001:2::/96 , this 96 -bit prefix is a predefined prefix for NAT-PT operations. The prefix can be customized, but the length must be 96 bits . This predefined prefix is ​​very critical, which is equivalent to pre-defining an IPv6 space for the IPv4 network on the right side of R2 . To give a very simple example, IPv6 single network protocol, if there are PC you want to access IPv4 single-protocol network PC , so a quick visit? What is the destination address? Can not let a IPv6 only the PC to ping an IPv4 address, right? So this /96 pre-defined prefix comes in handy, which can be understood as a predefined IPv6 address space served in the scenario for the IPv4 only network on the right .
