How to configure IP Helper for SCCM

Question

Now we are using DHCP options for PXE boot and we know Microsoft is recommended to use IP helper instead of DHCP options. How to configure it? Do we need to add an IP helper entry for each DP server as we have four PXE DP?

Answer 1

Hi,

Each PXE server should have an entry in the IP helper tables. That way, all the PXE servers will get the client boot discovery and request, and only the PXE that needs to respond will respond. The configuration is like this:

IP helper-address <IP address of DHCP server>

IP helper-address <IP address of PXE server>

IP forward-protocol UDP 4011

In an environment where there are multiple PXE servers, each PXE server will only reply to the clients that it cares about. In the case of SCCM, the SCCM PXE server only cares about its own clients and will only respond to those clients that have task sequence deployed to them.
