As an IPv4-to-IPv6 transition technology, ISATAP allows an ISATAP network node to send an IPv6 packet over an IPv4 network by encapsulating the packet in an IPv4 header without the need for a preestablished tunnel across the IPv4 domain. Once the sending node deter- mines the end point of the ISATAP tunnel, the IPv6 packet is sent to the nodes ISATAP tunneling interface for encapsulation in the IPv4 header, setting the value in the Protocol field to 41, which indicates the IPv4 header contains an IPv6 packet. When the device at the end point of the tunnel receives the packet, it reads the value of the Protocol field and knows to decapsulate the IPv6 packet from the IPv4 header prior to accessing the Transport layer protocol (TCP or UDP) and sending the application data up the OSI stack. Given this information, create a diagram of the ISATAP packet as it is sent across the tunnel from the source to destination nodes. Include individual cells in the diagram for the application data, the transport header, the IPv6 header, and the IPv4 header. Within the IPv6 and IPv4 head- ers, include information regarding the Next Header field, Source and Destination address fields, and the Protocol field. The illustration can be a high-level diagram, but it must show each of the fields at its correct location within each header.
