Multi-Layer Switch Inter-VLAN Routing

Multilayer Switch Inter-VLAN Routing is a method of inter-VLAN routing in which a different kind of switch known as a multilayer switch is used to perform routing functions. A multilayer switch is a hybrid device that combines the functions of a switch with a router, which enables it to operate on both Layer 2 (L2) and Layer 3 (L3) of the OSI model, hence the name multilayer. Unlike the router-on-a-stick inter-VLAN routing method, a multilayer switch inter-VLAN routing does not require a dedicated router—everything happens inside the switch. Multilayer switches perform all VLAN routing functions on the network, thereby replacing the need for dedicated routers or trunk links.
