I recently bought SG 300 28P to create the VLAN. My network hs 3 subnet 192.168.1.0, 192.168.2.0 and 192.168.3.0
My main net work is 192.168.1.0. I want to divide it to VLAN to eliminate the boardcast storm; especially from the domain 192.168.3.0
But I want all the devices from 192.168.1.0 to access other subnet.
Any suggestion where I can start from.
Thanks,

Hi,
for inter vlan routing you'll need a L3 device like a router or a L3 switch.
For the router you can use a router on a stick config:

Hi,
ok so you must have ip routing enabled and create as many SVIs' VLAN interfaces) as the number of VLANs and put the ip address of each SVI as the default gateway for hosts in that vlan.
