Q:
I as well appreciate the debate and love to discuss these issues. I have a feeling that neither of us can be detered in our thinking. Which is OK. If you find that teaching ARP at Layer 2 is necessary to get your point across, then far-be-it-from-me to contradict your teaching method. But, based on your statements in your last post I feel it necessary to leave with a few parting salvos:
1. You presented in an earlier post in this thread since this is a Cisco board lets see what Cisco has to say, or something to that affect, I agree, so here is a quote directly from the official Cisco Curriculum for the CCNA version 3, I believe version three is the most up to date version.
Cisco Global Learning Network, Cisco CCNA Semester 1 v3, Chapter 9, Section 9.1.4
"The following protocols operate at the TCP/IP Internet layer...IP, ...ICMP,...ARP,..., RARP"
It also provides a nice little graphic depicting the same.
And, Cisco Global Learning Network, Cisco CCNA Semester 1 v3, Chapter 9, Section 9.1.6
Shows a a graphic comparing the TCP/IP Model to the OSI Model, showing the Internet layer and the Network layer being in allignment, matching.
In the same chapter Cisco references this site
snnug.com/meetings/tcpip.htm which also shows ARP in Layer 3.
