Configuring Route Preferences using CLI Command For information about the CLI command that performs this function, see the following chapter in the CLI Reference Guide: • OSPF Commands VLAN Routing You can configure PowerConnect M6220/M6348/M8024 software with some VLANs that support 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 bridgerouter 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 only some of the VLANs on the port. 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 the PowerConnect M6220/M6348/M8024 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. The VLAN Routing menu page contains a link to a web page that displays VLAN Routing parameters and data. To display this page, click Routing > VLAN Routing in the tree view.
