Inter Vlan Routing Ccna Blog It is the default VLAN of switches. . You can assume multiple. To do so we need a layer 3 device and then we can implement inter-vlan by three ways- 1 Traditional inter-vlan routing 2 RoS Router on Stick technique 3 SVI Switch Virtual Interface this requires a layer 3 switch. Firstly we can use the traditional approach for this we need the physical router and we connect these to each VLAN to the different physical router interfaces. Hope this helps you. You can see above image the different VLANs in different switches which are connected with each other. For example if there is 10 VLAN then your router must have 10 physical ports to.
