Subject: VLAN configuration question


Hi,

	I need some assistance with a thorny networking scheme I'm
trying to implement.  Here's what I'd like to do:  I have two Cisco 3640
routers separated by a T1.  I want to set up a split-subnet VLAN on the
ethernet side of these routers.  See diagram.  The problem I'm having is
that the switch on the 3640(2) side of the connection is an unmanaged
D-Link with no VLAN capability.  Can I somehow perform this feat with my
setup? Would it be possible to have the 3640(2) router encapsulate data
(based upon MAC?) for the 10.30.50.100-103 machines and send across the
T1 link?  Ideas?  Thanks!

	  10.30.50.100-103
10.30.50.0/24 	       
       (VLAN on cat 3750)

Note also:  the catalyst 3750 is sitting on physical subnet
10.24.50.0/24.
