Basic VLAN Trunking in Debian based Linux.

Goal of Lab

  • Create sub-interfaces with VLAN tagging enabled

Scenario

Step 1

The first thing you'll want to do is install the VLAN package using aptitude.

aptitude install vlan

Note: if aptitude can't find the package, use the command "aptitude update" before trying to install the package.

Step 2

Load the 802.1Q module into the kernel

sudo modprobe 8021q

Then verify the module has been loaded into the kernel

lsmod | grep 8021q

The output on your screen should look similar:

Step 3

Use vconfig to add VLANS

vconfig add "interface" "vlan"

Step 4

Configure IP Addresses on the sub-interfaces.

ifconfig "interface.sub-interface" "ip address" netmask "subnet mask"

Step 5

Configure the default gateway for each sub-interface / VLAN

route add -net "ip address" netmask "subnet mask" gw "default gateway"

The server should now be trunking VLANS 10,20,30, and 40 on eth0
