I have cisco IOS DHCP server configured on a 2960G switch on Vlan 20. I have added a "IP helper-address" on the SVI of the switch for our Ghost server which is on a different subnet (Vlan 70) to the switch. I'm trying to do a PXE Boot to the ghost server but the hosts on Vlan 20 do not get assigned an IP from the switch when it is doing the PXE boot.
Can you please give me some advise on why this is not happening and please help me with the config?
1. Remove the IP helper address. PXE clients send an Option 60 in the DORA process to identify themselves as PXE clients. Your DHCP then points them to the location of a PXE server (Ghost). You can set this up on the IOS DHCP server as below.
2. ip dhcp pool VLAN20
network x.x.x.x x.x.x.x
option 60 ip x.x.x.x
This will assign client the normal IP address, and if Option 60 is determined will tell them them the address of the Ghost server.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
