I'm using two C3 series switches. I was hoping the switches would limit broadcast traffic but still allow communication over seperate VLANs by transferring packets over egress ports until reaching the switch that was directly connected to the destination, and then automatically route it to the new subnet/VLAN based on ARP tables. Admittedly I've not been entirely sure how that part works and was hoping it was similar to communication between subnets over separate router interfaces. In this case I want to separate offices and organizational groups by VLAN, but still allow everyone access to a few central data servers on a seperate VLAN. What is the best way to go about this?
