I would not call that a problem.  By the nature of a Switch it's a layer
2 device.  There needs to exist somewhere in the network a layer 3
Router to handle the communication of packets between VLANS/subnets.
While you can save some money by going with options like the 3com
hardware mentioned, I would prefer to use hardware designed for specific
tasks.  i.e. a switch to handle my switching, and a router to handle my
routing.  

Just my 2 cents..

The problem with using a Cisco 2900 is that it supports port VLAN
tagging, but does not support layer 3 switching.  That means that for
VLANs to intercommunicate, you must install a router which interconnects
each VLAN.  That adds significant cost.

Layer 3 switches tends to be very costly.  The most cost effective Layer
3 solution I have discovered is 3Com 3300 SuperStack 3 with the optional
layer 3 module.  The switches are about $1200 and the layer 3 module is
$1400.  You can stack up to four using a matrix module and they all
inherit layer 3 functionality from the layer 3 module.  This may not be
the most favored equipment, but addresses the requirements of a small
company environment (minimizing cost).

Hope this is helpful,

Dave Brown

That's a great choice.. I'd stick with that.  We've deployed a 3500 node
network with 200+ cisco switch's using multiple vlan's.  In this case
cisco is the only choice.  I recommend however, that you trunk your
Vlan's using dot1q instead of ISL incase you ever use non-cisco gear (or
just to be industry standard compliant).
