Hi gents! I have an issue with my dhcp topology. I'm not quite sure of how it is configured, the fact is all the routers have this configured at their interface
interface FastEthernet0 ip address 192.20.3.253 255.255.255.0 ip helper-address 17.21.4.117 ip helper-address 17.21.4.118 ip ospf network point-to-point
The ip helper-address is the dns & dhcp address. So I wondered if this is the piece of code that makes all my routers ask for dhcp leases for the clients to the domain controlers. Sorry for not explaining better, ask as much as you want.
