I’ve tryed with some cheaper switch from Allied Telesis this schema using Protected Vlan. The problem I’ve encounter is than with Protected Vlan you can’t define vlan’s and only the traffic for vlan 1 is passing throw the switches.
I’ve been reading some articles and if I understand well I should need some switch with Private Vlan. Is this correct ? If yes if we suppose a second hand switch with only 2Gb ports should be enough, what switch should I’ve to buy ? For what I know at least a 3560.
If we decide to buy a new switch what model of switch do we need ?
To finish it’s possible with this switch to limit the traffic on the vlan 1 to be only a PPOE traffic ?
