Will this configuration work?

L1 Bithead

I will configure 14 VLANs in total. I will connect all Firewall Interface to one of the L2 Switch and I will cascade the other L2 Switches with that L2 Switch. In this case, do we need Trunk? Please check if any problem with such configuration.

There will be no L3 switch and the Firewall will do all the routing.

you can connect all the links from the firewall to the switch, in case if you're connecting to the same switch then you can do a port-channel between switch and firewall, in the firewall, you can configure the sub-interfaces for all VLANs, in the switch just configure the port-channel as a trunk, it should work fine for you

If the connections to the first switch have multiple vlans, then yes you should use a trunk. Then do as @Basavaraj suggests and make the physical interfaces layer2 with layer2 subinterfaces. Then make your VLAN the layer3 interface.


Hope that makes sense.
