[comp.protocols.appletalk] ethertalk specifications

Is there a document that describes Appletalk over ethernet?
I want to examine the routing packets on the ethernet but
I'm not sure how to decode the packet.

The document you want is titled "EtherTalk and Alternate AppleTalk
Connections Reference" available from APDA for $20.  The order
number is M7056.  You may also want "AppleTalk Phase 2 Protocol
Specification:  An Addendum to Inside AppleTalk" and "Inside AppleTalk".

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!
