I need to create a 2nd domain, but would like to run it on the same subnet since all the deivices on both domains need to talk to each other for file and print. Can this be done? If I configure the DHCP scope to give out 1 DNS server in each domain with pointers back to the other domain can this work?? This only needs to run like this for approx 3 years and then the first domain will come down after all the users have migrated out of it. I'm trying to avoid having to re-configure all the switches with an additional VLAN with ACL's and routing rules.
