I'm not sure exactly what you are describing, but the first question in my mind is what MAC address would be in the source field of the frame going to VLAN 2. Could make for some pretty confused ARP tables. Would the IP address have to be rewritten if it now corresponds to a different MAC address? >If the answer is no, Are there switches on > >the market that is routing by this concept, please advice , What problem are you trying to solve?
