Multiple instances of the same tag may occur in the system; only the first occurrence is used by the system. By precedence, we mean that data is read first by processing (1), when that is done, (2) is processed, followed by (3). Any option that is defined is not replaced by subsequent sections.

Chapter 2
Since an option can potentially be provided in three places (standard DHCP
packet, option 43, and via TFTP with option 18), the precedence rule is defined as:
(1) standard packet, (2) option 43, and (3) TFTP via option 18. Multiple instances of
the same tag may occur in the system; only the first occurrence is used by the
system. By precedence, we mean that data is read first by processing (1), when
that is done, (2) is processed, followed by (3). Any option that is defined is not
replaced by subsequent sections.
