Configuring Routing 531Configuring Route Preferences using CLI CommandFor information about the CLI command that performs this function, see the following chapter in theCLI Reference Guide:• OSPF CommandsVLAN RoutingYou 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 routerport.When a port is enabled for bridging (default) rather than routing, all normal bridge processing isperformed 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 packetis 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 allof the VLANs on the port or for only some of the VLANs on the port. VLAN Routing can be used toallow more than one physical port to reside on the same subnet. It could also be used when a VLANspans multiple physical networks, or when additional segmentation or security is required. This sectionshows how to configure the PowerConnect M6220/M6348/M8024 software to support VLAN routing. Aport can be either a VLAN port or a router port, but not both. However, a VLAN port may be part of aVLAN that is itself a router port.The VLAN Routing menu page contains a link to a web page that displays VLAN Routing parametersand data. To display this page, click Routing > VLAN Routing in the tree view. The following web pageis accessible from this menu page:• VLAN Routing Configuration• VLAN Routing Summary
