Q:
5 - segments of network media (physical)
4 - repeaters or hubs
3 - three host segments of the network
2 - two link segments (no hosts)
1 - one large collision domain
These rules of thumb are used for ease of staying within the roudtrip delay calculation for a particular physical medium and the encoding for that type of medium. So odviously, if you put a bridge within an all repeater network the collision domain will be broken into atleast two segments depending on the number of interfaces on the bridge and the number of those interfaces being used. However, a bridge will forward all broadcast packets by default as will a switch. Moreover, this forwarding function is transparent to all other devices on the network staying within the concept of direct routing. And since ARP uses a broadcast function, why do you say ARP only works within a collision domain?
As far as other sources, actually yes I would love other sources. If I am wrong I would like to figure out why I am wrong. So, if you have a couple of clear concise references outlining the concepts of why ARP is at Layer 2, I would love to see them.
