Create Source Route - 0x21
Description
This frame creates a source route in the device. A source route specifies the complete route a packet
traverses to get from source to destination. For best results, use source routing with many-to-one
routing.
Note Both the 64-bit and 16-bit destination addresses are required when creating a source route.
These are obtained when the device receives a Route Record Indicator (0xA1) frame.
Format
The following table provides the contents of the frame.
