Hello!

Well, one device for all virtual lans determining how to deliver
to a particular vlan via some internally saved information or 
stored in routing/neighbor tables. F.e. remembering ID of VLAN
as sort of destination MAC address and fetching real information,
including real MAC addresses from an internal table.

I remember, one guy tried to work with about thousand of tunnels.
It works, but it is painful even to type ifconfig: too long output 8)
And traceroute dumps out 8)
