Configure VLAN Routing with Static Route
VLAN Routing Overview
VLANs divide broadcast domains in a LAN environment. Whenever hosts in one VLAN need
to communicate with hosts in another VLAN, the traffic must be routed between them. This is
known as inter-VLAN routing. On NETGEAR switches it is accomplished by creating Layer 3
interfaces (switch virtual interfaces [SVI]).
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 can also be used when a VLAN
spans multiple physical networks, or when more segmentation or security is required.
A port
can be either a VLAN port or a router port, but not both. However
, a VLAN port might be part
of a VLAN that is itself a router port.
Sample VLAN Routing Configuration
To configure a switch to perform inter-VLAN routing:
1. Use the VLAN Configuration screen to enable routing on the switch.
For more information, see VLAN Configuration on page 82.
2. Determine the IP addresses 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 or 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. Configure the VLAN interfaces by using VLAN configuration screens.
For information about this, see
Sample VLAN Configuration on page 255 Assign the
VLAN the IP address identified using the VLAN routing configuration, for example, IP
address 10.1.2.1 and mask 255.255.255.0.
4. Repeat this process for all VLANs to be configured as routing interfaces.
