When a port is enabled for bridging (the 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.
Because 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. A port can be either a VLAN port or a router port, but not both. However, a VLAN
port can be part of a VLAN that is itself a router port.
Complete these steps to configure a switch to perform interVLAN routing:
1.
Use the IP Configuration page to enable routing on the switch.
For more information about this step, see
Configure the router settings on page
2.
Determine the IP addresses that you want to assign to the VLAN interface on the switch.
For the switch to be able to route between the VLANs, the VLAN interfaces must be
configured with an IP address. When the switch receives a packet destined for another
subnet/VLAN, the switch looks at the routing table to determine where to forward the
packet. The packet is then passed to the VLAN interface of the destination. It is then sent
to the port where the end device is attached.
3.
Use the VLAN Routing Wizard page to create a routing VLAN, configure the IP address and
subnet mask, and add the member ports.
For more information about this step, see
Create a routing interface with the VLAN Static
In the following figure, VLAN 70 is a routing interface VLAN with IP address
203.0.113.118 and subnet mask 255.255.255.0. For information about viewing the
member ports of the VLAN, see
