O le exampO lo'o fa'aalia ai le auala e o'o mai ai le tele o VLAN i le router i luga o le Layer 3 port. O nei felauaiga uma e fesoʻotaʻi i luga o se masini komepiuta ATM e tasi i le DSLAM ma le kamupani e tuʻuina atu auaunaga tagged ma a
tasi VLAN tag. O tuatusi WAN ma LAN IP e tuʻuina atu e le DHCP servers.

O lenei topology o loʻo faʻaalia i le ata o loʻo i lalo.
