VLANs on Linux (Linux Journal)VLANs on Linux (Linux Journal)Posted Mar 24, 2004 1:28 UTC (Wed) by gavino (guest, #16214)In reply to: VLANs on Linux (Linux Journal) by gerdesj Parent article: VLANs on Linux (Linux Journal) In reply to "what have VLANs done for us?" I run a computer training company with currently 7 rooms of PCs. Each room needs access to a DHCP server and access to the Internet. Each room has to be totally seperate from one another. This is because in the trainingrooms everyone runs as Administrator and with no password, for ease of Administration. This is a training environment, not a production environment so this is OK. The manchines get re-ghosted at least once a week. OK. So with VLANs we can use one layer-3 backbone switch and we can have one DHCP server servicing all VLANs, and we can have one interface on our router which can provide Internet access for all VLANs. VLANS means we don't have to have a seperate DHCP server in each room, or a seperate router for each room, nor have a single router but with serveral physical interfaces. VLANs are great!
