Subject: [dhcwg] DHCP Option "Server Identifier"

Hello,
 
I'm hoping you can clarify what seems to be a conflict between RFC 2131 and RFC 2132.
 
On page 29 of RFC 2131 within "Table 3:  Fields and options used by DHCP servers" it indicates that option "Server identifier" MUST be present in DHCPOFFER, DHCPACK, DHCPNAK messages.
 
On page 27 of RFC 2132 in section "9.7 Server Identifier" it says "This option is used in DHCPOFFER and DHCPREQUEST messages, and may optionally be included in the DHCPACK and DHCPNAK messages."
 
Thus my confusion:  If the Server Identifier option is a MUST for DHCPACK and DHCPNAK, how can it be considered optional for DHCPACK and DHCPNAK?
 
Your interpretation and clarification will be appreciated.  Thanks.
 
RSVP
