Multiple Port-Based Vlans - Dell PowerConnect B-FCXs Configuration Manual

Configuring the same IP subnet address on

multiple port-based VLANs

For a Dell PowerConnect device to route between port-based VLANs, you must add a virtual routing
interface to each VLAN. Generally, you also configure a unique IP subnet address on each virtual
routing interface. For example, if you have three port-based VLANs, you add a virtual routing
interface to each VLAN, then add a separate IP subnet address to each virtual routing interface.
The IP address on each of the virtual routing interfaces must be in a separate subnet. The Dell
PowerConnect device routes Layer 3 traffic between the subnets using the subnet addresses.
NOTE
This feature applies only to Layer 3 Switches.
NOTE
Before using the method described in this section, refer to
routing interface groups"
methods in that section instead.

As shown in this example, each VLAN has a separate IP subnet address. If you need to conserve IP
subnet addresses, you can configure multiple VLANs with the same IP subnet address, as shown in
