It's not only possible, it's automagic !
If the only thing you look at is the relay agent address (GIAddr,
Gateway Interface Address) then all the class membership will tell
you is which physical the client is connected to - including which
VLAN as VLANs are treated just the same as multiple real LANs. The
server will automagically take care of only assigning addresses to
clients from pools which are appropriate to the physical network.
If this isn't working for you then post your config and we can take a
look, but fist, check that you haven't used a shared-network where
you shouldn't have (VLANs are NOT a shared network).
