Hi all. I am new to VLAN's. I have a requirement, and I want to know whether it is technically possible to do.
I have a link coming over Cat6, from ISP to my switch. Network
10.1.23.0 / 24I have few switches in my premises. cisco 3560, 2960.
For certain of my applications, I need to create seperate VLAN's.as i understood, every VLAN has to be a seperate subnet. Could I subnet the existing network of
10.1.23.0 into multiple subnets. / 28 or / 30 according to my needs internally, and create seperate VLAN for each subnet, and they will still talk to the ISP core switch as it were a / 24 network. I could do this and get it to work if it was purely for LAN purposes, however, the Core switch of ISP links me to my WAN (remote networks 10.1.1.0 ~ 10.1.22.0, 22 locations ) ..each IP in this network needs to talk to every other network, and the vice versa. I know that if i do not subnet the network, it works fine as a single VLAN.
Is there any way that I could have multiple VLAN's and still have connectivity to and from my other networks, using same subnet or a subnetted subnets ??
Thanks in advance
