Inter-VLAN routing

Inter-VLAN routing is a process that enables devices on different virtual local networks (VLANs) within the same physical network to communicate with each other. Think of VLANs like separate groups or departments within an organization, each with its own designated space. Routing acts like a translator or bridge, allowing these groups to share information when needed, despite being separated virtually. This is typically handled by a network device called a router or a layer 3 switch, which manages and directs the traffic between VLANs efficiently and securely.
