RE: DHCP Client-identifier option for DHCPOFFER

Hello Fabian,
 
From RFC 2131 Section 4.1:
The 'xid' field is used by the client to match incoming DHCP messages
   with pending requests.  A DHCP client MUST choose 'xid's in such a
   way as to minimize the chance of using an 'xid' identical to one used
   by another client.

Subject: [Ipoverib] DHCP Client-identifier option for DHCPOFFER



Hello all,

 

RFC2131, Section 4.3.1, Table 3 indicates that the client identifier option
"MUST NOT" be used in DHCPOFFER messages sent by the server.  Since the
DHCPDISCOVER message must have the broadcast flag set, the DHCPOFFER message
will be broadcast back.  How do recipients of DHCPOFFER tell if they are the
intended target?

 

Thank you,

 

Fabian
