VLAN routing interface example
configuration
VLANs divide broadcast domains in a LAN environment. When hosts in one VLAN must
communicate with hosts in another VLAN, the traffic must be routed between them.
This is known as inter-VLAN routing. On the switch, it is accomplished by creating Layer
3 interfaces (switch virtual interfaces [SVI]).
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 and VLAN ID are used to search the MAC address table.
If routing is enabled for the VLAN, and the MAC destination address 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 routing 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 itself functions as a router port.
In this example, you do the following:
1. Enable the IPv4 routing mode.
2. Use the VLAN Static Routing Wizard to create a routing VLAN with VLAN ID 50,
configure the IP address as 192.168.200.20 and the subnet mask as 255.255.255.0
for the routing VLAN interface, and add ports xg7 and xg8 as untagged members
of the routing VLAN.
To configure the VLAN routing interface example:
1. Connect your computer to the same network as the switch.
You can use a WiFi or wired connection to connect your computer to the network,
or connect directly to a switch that is off-network using an Ethernet cable.
2. Launch a web browser and enter the IP address of the switch in the address field of
your web browser.
If you do not know the IP address of the switch, see Access the switch on-network
and connected to the Internet on page 25 or Access the switch off-network and not
connected to the Internet on page 32.
