Inter-Vlan Routing - Supermicro SSE-G24-TG4 Configuration Manual

IP Routing is not supported on loopback interfaces.
The "nointerface loopback <interface-id (1-100)>" command deletes the loopback
interface.

1.3 Inter-VLAN Routing

VLANs enable splitting traffic across several manageable broadcast domains. Devices within a VLAN can
communicate with one another without requiring routing. Whenever hosts in one VLAN need to
communicate with hosts in another VLAN, the traffic must be routed between them. This is known as
Inter-VLAN Routing.
Supermicro switches use application-specific integrated circuits (ASICs), which are hardware chips that
can route traffic at very high speeds. These ASICs are installed on the switching engine of a Layer 3
switch, which traditionally switches frames at Layer 2. The ASICs allow the switching engine to also
switch frames that contain packets sent between different VLANs. Each ASIC is programmed with the
information required to route traffic from one VLAN to another, without having to pass the traffic
through the CPU of the routing engine.
