Static Routing

3.2 VLAN-based Router-Interface

A characteristic of the VLAN-based router interface is that a number of devic-
es in a VLAN are connected to different ports. The devices within a subnet
belong to one VLAN
Within a VLAN, the Switch exchanges data packets on the layer 2 level.
Data packets with a destination address in another subnet address the
terminal devices to the switch as a gateway. This then exchanges the data
packets on the layer 3 level.
Below you will find an example of the simplest case of a routing application
with VLAN-based router interfaces. For the VLAN 2, the router combines
ports 3.1 and 3.2 into the VLAN router interface 9.1. A VLAN router interface
remains in the routing table until at least one port of the VLAN has a
connection.

Switch to the Priviledged EXEC mode.
Switch to the VLAN mode.
Create a VLAN by entering the VLAN ID. The
VLAN ID is between 1 and 4042 (MACH 4000:
3966).
Assign the name "Gerhard" to VLAN 2.
Create a virtual router interface and activate the
router function at this interface.
Switch to the Priviledged EXEC mode.
