Example-VLANs

Authors: Ferm&iacute;n Gal&aacute;n (galan at dit.upm.es) version 1.7, November 23rd, 2006

Scenario
This example shows four simultaions to be executed concurrently. First ([vlan-test-1.xml vlan-test-1]) boots three virtual machines, each one connected to one VLAN in the host physical interface eth1 (in particular VLANs 10, 22, and 23). The other three simulations ([vlan-test-2a.xml vlan-test-2a], [vlan-test-2b.xml vlan-test-2b] y [vlan-test-2c.xml vlan-test-2c]) boots one virtual machine each one, connected to one of the three VLANs. Note that the same is used for vlan-test-1 and the correnponding vlan-test-2X. In all the case, eth0 is the physical interface where the VLANs will be created.
