I just wanted to add that while the above-mentioned document will give you the 
specs for how an AppleTalk packet is encapsulated within an Ethernet packet, 
the book "Inside AppleTalk" (Addison-Wesley, 1989) actually give the formats 
for the RTMP (Routing Table Maintenance Protocol) packets that Phil is 
actually interested in.  "Inside AppleTalk" also includes the AppleTalk-to- 
Ethernet information, but not the details on programming the EtherTalk 
interface given in the "EtherTalk...Reference".

Hope this helps!
