Configuring InterVLAN routing on the Cisco router. IP Address - 192.168.1.2 Subnet Mask - 255.255.255.0 Gateway - 192.168.1.1 Check whether all computers are communicating now. If you’re doing this on a simulator like Cisco Packet Tracer, turn on simulation mode and see how the packets are traveling. Legacy inter-VLAN routing, the router on a stick and layer 3 switches. As mentioned earlier, Router is needed to set up the legacy inter-VLAN routing. Specially each plan has separated physical interfaces that connected to the router. So connection mode between router and switch should not be in the trunk.
VLAN is the concept of using multiple LAN over switches or routers. Each VLAN has it's own broadcast domain and has different subnet id. So you can create multiple VLANs and allocate different subnets thus increases the security. I already mentioned that each VLAN has it's own subnets id so you need a layer 3 device namely router to send packets between these VLANs. This is called inter-VLAN routing, this can be done in three ways.
Legacy inter-VLAN routing, the router on a stick and layer 3 switches. As mentioned earlier, Router is needed to set up the legacy inter-VLAN routing. Specially each plan has separated physical interfaces that connected to the router.
So connection mode between router and switch should not be in the trunk. The problem here is the number of VLANs to be depended on the number of physical interfaces on the router. But it can access the full bandwidth of the physical interface.Here we didn't. Let's we see how to configure legacy inter-VLAN routing.
