Example
You must order intermediate hop addresses starting with the neighbor of the destination and working
closer to the source.
Suppose a route is found between A and E as shown in the following example.
A ' B ' C ' D ' E
If device E has the 64-bit and 16-bit addresses of 0x0013A200 40401122 and 0x3344, and if devices B,
C, and D have the following 16-bit addresses:
B = 0xAABB C = 0xCCDD D = 0xEEFF
This example shows how to send the Create Source Route frame to establish a source route between
A and E.
