I have several switches in my public network each connecting two or

understand. I was wondering if anyone does this and how to make it
secure.
Thanks.
Essentially you are talking about creating the vlans centrally, using
VTP to propagate out the VLANs, using your existing routers to service
those networks (or perhaps consolidate those as well to a central l3
switch or router). This isn't that difficult, and it depends if you
are consolidating onto a catalyst or ios based switch for config
references. You also would need to control 'security' at the
routers. If you don't want traffic between subnets, you'll need to
ensure that you aren't advertising the networks between you routers,
or you have access-control lists if you are routing centrally.
