router on a stickRefer to curriculum topic: 6.3.1With router on a stick, subinterfaces are used on one physical router interface. One subinterface per VLAN is used in this design. When multiple interfaces are used on a router, each physical interface such as Gi0/0 and Gi0/1 is assigned one IP address. Each VLAN would require a physical interface. When routing via a multilayer switch, one SVI is assigned an IP address for each VLAN. Interdomain routing does not affect inter-VLAN communication. Explanation: The topology in the exhibit uses router-on-a-stick inter-VLAN routing. This implementation uses a single router with multiple subinterfaces, one for each VLAN. The router uses a Layer 2 trunk link to connect to a switch, which in turn connects to the devices in each VLAN. The router performs all inter-VLAN routing.
