I have a LAN-A with VLANs 10,15 and a layer 3 switch-A used to communicate between VLANs 10 and 15. This LAN is working OK.
I have a LAN-B with VLANs 60,65 and a layer 3 switch-B used to communicate between VLANs 60 and 65. This LAN is working OK too.
Question: Do I need an additional layer 3 switch or an additional router to communicate devices between LAN-A and LAN-B? (let's say vlan 10 device with vlan 60 device). Or can this be achieved just by configuring switches A and B?
Thanks. Arthur
