Hi everyone,
Hope all are being safe and sound !!
Need someone experience in setting up ip helpers for pxe boot as we are trying to establish the same in our environment but having some issues.
Since we have our VLAN ranges and WDS server on a different subnet and due to cost constraints we can’t set up a local WDS for this range we thought about going for up helpers for it.
It’s already configured on switched by our network team but need someone expertise with the below :
after adding the VLAN scope in our DHCP server do we still need to keep option 66 and 67 enabled or disable??
if we implement IP helper from the network side and keep the option 66 and 67 enabled at DHCP would it mess with the functionality?? Is it mandatory to get them to disable??what are the changes we should be doing at the DHCP side for this pxe boot using IP helper?
Regards

You need to get rid of any and all DHCP options related to PXE boot.
HI Jason,
Thanks a lot for this beautiful article that broke down the complexity into small pieces but I had one point to clear though which I could not find in this article so hoping you could help me out here.
If we choose to implement IP helper should be disbale option 66 and 67 in DHCP server? if we keep both IP helper and DHCP scope option would both of them conflict?
Also In DHCP side we just only have to add the VLAN ranges or any other kind of changes are required?
Hope you help me figure this one out :).

As noted in my original reply, yes: "You need to get rid of any and all DHCP options related to PXE boot."
HI Jason,
Everything is clear now :). Thanks a bunch for your expertise and sharing the experience.
So on DHCP side we just need to add the VLAN ranges of the IP subnet that we want to support for PXE boot and that's it we are good to go right ?

Yes, DHCP must issue IPs for PXE to work so standard DHCP configuration is still in order.
