I have a situation here which I need help on.
We have 3 VLAN's here. All 3 VLAN's are connected to a Catalyst switch and then to a router via E0.
We have DHCP servers installed on each VLAN which provides to each subnet/vlan.
We are shutting two of them down and we only want to use 1 DHCP server for all 3 VLAN's/Subnets.
I was told that I must configure the IP Helper configuration on the router's E0 interface which is connected to the switch pointing to the DHCP server.
Is there any additional steps required for this to work?
I was told by someone else that some relay configurations must be made to the VLAN's on the Catalyst switch to point to the correct DHCP server for requests?
