I have sliced up my new subnet as follows
Datacenter - 10.10.1.x/24
Everything in the data center will be static from this subnet
Outside the data center - 10.10.2.x/23
This will include switches, printers and users
Now the DHCP server is obviously going to be sitting on 10.10.1.x/24 but will need to hand out 10.10.2.x/23 addresses.
On my layer 2/3 switch I have multiple interfaces on VLAN1 and I believe all I need to do is on the VLAN1 interface
ip helper-address 10.10.1.253 (this is the IP of the DHCP server)
And that should be that yes?
