You can configure D-Link software with some ports supporting VLANs and some supporting routing. You can also configure
the software to allow traffic on a VLAN to be treated as if the VLAN were a router port.
When a port is enabled for bridging (default) rather than routing, all normal bridge processing is performed for an inbound
packet, which is then associated with a VLAN. Its MAC Destination Address (MAC DA) and VLAN ID are used to search the
MAC address table. If routing is enabled for the VLAN, and the MAC DA of an inbound unicast packet is that of the internal
bridge-router interface, the packet is routed. An inbound multicast packet is forwarded to all ports in the VLAN, plus the
internal bridge-router interface, if it was received on a routed VLAN.
Since a port can be configured to belong to more than one VLAN, VLAN routing might be enabled for all of the VLANs on
the port, or for a subset. VLAN Routing can be used to allow more than one physical port to reside on the same subnet. It
could also be used when a VLAN spans multiple physical networks, or when additional segmentation or security is required.
This section shows how to configure D-Link Unified Switch software to support VLAN routing. A port can be either a VLAN
port or a router port, but not both. However, a VLAN port may be part of a VLAN that is itself a router port.
