Do I need a router
-
Hi,
I am investigating the following oppertunity:we have a WAN with for example a C-class of public IP's.
<wan>- Main Switch –- Switch A
|
Switch Ba) The IP's are spread over Switch A & B (C....) All connected to the main switch.
b) The clients connected to Switch A & B (C....) get the external address (no NAT)
c) The Switches are Layer3
Question:
Will The clients in Switch A be able to connect to the clients on Switch B without going through the WAN ?</wan>

answering would be simplier if you have had router. with router wan-link would be unused in this scenario
L2/L3 switch should have same functionality, it looks arp table where is this ip-address and send the packet straight there.
Answer in short: you should be ok without router
