Typically you would use a private VLAN between you and another =
participant in order to connect to them separately from the public =
peering VLAN. You would do this instead of a PNI in a situation where =
you=E2=80=99re in a different building from the other participant making =
a direct fibre more expensive than the value it would bring.
A public VLAN is essentially the peering VLAN anyway, so an all =
participants VLAN would be a little pointless. Perhaps a VLAN shared =
between a couple of members *may* be useful depending on those =
members=E2=80=99 use cases, although I can=E2=80=99t think of one off =
the top of my head.
