In order to compensate for the single vlan tagging on the .100 interface and the double tagging on the .200 interface, the vlan MTU is increased to 9204 and then to 9208 bytes respectively.  There is no need to adjust for the vlan tags.

I've heard this referred to as 'dynamic MTU adjustment', though I don't know if there's actually a formal name for it.
