Vlan separation

[Rashmiranjan jena]

In my server switch one vlan is creeated and that is 10.101.190.0/24 and firewall is connected then firewall is connected with my core .

i want to some ip address of server series in my core ,

how will be created and how it's possible.

If all your device are in one subnet (10.101.190.0/24) than you can extend the same vlan to your core and connect your end devices to the core in the same IP range.

So the topology is like this?

Server Switch > Firewall > Core?

If so, the only way to extend the subnets across the Firewall is to make it transparent. I am guessing its a routed firewall which means you need a different subnet on each side. If you create the same VLANID on the core and the firewall is in routed mode, it will have problems knowing how to forward packets for that subnet as it will exist on both interfaces,
