	Sender: tcp-ip-relay@nic.ddn.mil
	To: tcp-ip@nic.ddn.mil

	Is there any standard for how a TCP/IP implementation ignores options
	that it does not understand and/or implement?

Dale,

Yes.  Please see sections 3.2.1.8, 4.1.3.2, and 4.2.2.5 of RFC-1122 for option
processing in IP, UDP, and TCP, respectively.
