A small college uses VLAN 10 for the classroom network and VLAN 20 for the office network. What is needed to enable communication between these two VLANs while using legacy inter-VLAN routing?
A router with at least two LAN interfaces should be used.*
- Two groups of switches are needed, each with ports that are configured for one VLAN.
- A router with one VLAN interface is needed to connect to the SVI on a switch.
- A switch with a port that is configured as trunk is needed to connect to a router.
Explanation: With legacy inter-VLAN routing, different physical router interfaces are connected to different physical switch ports. The switch ports that connect to the router are in access mode, each belonging to a different VLAN. Switches can have ports that are assigned to different VLANs, but communication between VLANs requires routing function from the router.
