Implementation of ISATAP Protocol and Wireshark

Can anybody help me how to implement ISATAP packet ? I'm creating packets in C++ (Winpcap). I can't imagine how it should be.

Specification: http://www.networksorcery.com/enp/protocol/isatap.htm

Is that example of ISATAP packet ?

0000 5EFE
C0A8 0110 (IP Address - 192.168.1.16)
4548 9559 (Some data)

Because, when I open .pcap in Wireshark, it don't recognize that.
