[c-nsp] vlan trunking on BSD machines and a little of MPLS

[insan praja]

Dear all,
I'm trying to setup a vlan trunking between 3 BSD
machines, I understand that in cisco switches, if I
have 3 vlan capable switches, I could spann a vlan
from one switch to another w/o changing its network. I
wonder if I could do that on bsd machines. I using
NetBSD and FreeBSD. 
One thing i'd like to ask you guys..
Which is more effective in a distribution layer, MPLS
or a VLAN trunks with dot1q/p?
Thanks,


Insan
