2 DHCP server same subnet
Hello All. I have what is likely to be a simple question (I think). We have a corporate network in one building and it has a mask of 255.255.0.0 because there are alot of devices on that network. ...
Hey,
Thanks for the thorough explanation :)
The "real" answer is of course to segment via VLANs. I understand you are not in a position to do so at the moment. What you can do instead is use DHCP snooping, as you mentioned yourself. Basically, configure the switch in the new building to use DHCP snooping and then only trust the port where the DHCP server, for building 2, is. That will essentially discard DHCP replies on any other port.
In the long term, the company should consider making plans to implement VLANs. With large networks, broadcast will eventually become an issue. Something to maybe plan for!
Cheers
