Hello! I have a little question:

What happens (or might happen) when I connect the N cable and client c1 wants to talk to client c3?


Internet
|
Proxy
|
switch1
|......|____________
|..........................|
switch20........switch21
|....|....|__N__|...|...|
c0..c1...............c2..c3

Please ignore the dots (it was the only way to avoid conversion of more white characters into one)

cx - clients on the LAN
switchx - unmanaged switch (dumbest kind )

I have two answers but I would like to know others' opinions...

1. the traffic doubles up, as there will be two ways for the packets to go through;
2. the traffic through switch1 lowers as a shorter path is found on the LAN
and the switch1 will be used only for Internet trafic.

(I am closer to thinking that the answer 1 is the correct one.)

Please argument your option. If you don't have an argument please don't post.

a link to docs would be also ok
