Multicast

Broadcasting a message to a group of nodes involves creating a group table entry for a specified end-point and group

ID. Refer to Section 6.4.3 Multicast transmission in [1] for

implementation specifics.

Sniffer log, multicast.dcf, shows a multicast transmission from coordinator to Group 1 and end-point 0xF0 in #34.The

network destination address is the group address.

Multicasts do not have APS Acknowledgements and are re-broadcast by all routers (group members and non-

members) until the radius is exhausted. Figure 4-13 shows the non-member radius w

hich is decremented on every non-

member re-broadcast of the frame.
