These are two different things…
66 and 67 tell a pxe client where to get the tftp image. In bsa, the pxe server will hand these out after talking w/ the bsa db. you cannot use the dhcp server to hand these out.
211 and 212 are used after the target has booted into a pre-boot environment to tell bmi how to talk to the bsa appserver. if they won’t create them in the dhcp server, then you can setup pxe in the ‘multi-db’ mode (but w/ just 1 db) and have pxe also hand out 211 and 212. But then you must disable auto-discovery. So it’s better to create the 211 and 212 options and set in the dhcp scope.
