I dont quite see why you need "router on a stick" in this situation to have
PC1 talk to PC2???
Because you have 2 different hosts sitting on 2 different switches, the 2
broadcast domains are segmented alread for you.
PC1 would arp for its gateway address (which is the router) via switch1 (who
forwards the arp broacast to the router), router replies the arp. PC1 sends
its frame with PC2's IP address (as the destination IP) and the routers mac
address. Router recieves the frame, strips off the mac information, sees
PC2's IP address as the destination, arp for PC2's mac address (if it doesnt
already have this in its arp table), prepares the frame with the source and
destination mac and IP addresses and sends it out the interface connected to
PC2. This is all without any need for a router on a stick.
Anyways, there you are Nouman.
