Detailed explanation-1: -What is a characteristic of legacy inter-VLAN routing? Only one VLAN can be used in the topology. Inter-VLAN routing must be performed on a switch instead of a router. The user VLAN must be the same ID number as the management VLAN.
Detailed explanation-2: -The “router-on-a-stick” inter-VLAN routing technique needs only one physical interface to route traffic among multiple VLANs on a network. A router’s physical interface is configured as an 802.1Q trunk and connected to the Layer 2 switch’s trunk interface.
Detailed explanation-3: –The first inter-VLAN routing solution relied on using a router with multiple Ethernet interfaces. Each router interface was connected to a switch port in different VLANs. The router interfaces served as the default gateways to the local hosts on the VLAN subnet.
