	Title		: Redundant Address Deletion when Encapsulating IPv6 in 
                          IPv6

In some potentially common uses of IPv6-in-IPv6 encapsulation 
('tunneling'), a node that is performing an encapsulation or 
decapsulation will also be the source or destination of the packet 
being encapsulated.  That can result in the same IPv6 address 
appearing in both the outer (encapsulating) and inner (encapsulated) 
IPv6 headers.  This document specifies a method for deleting such 
redundant addresses from an inner header when performing an 
encapsulation, and restoring those addresses when decapsulating, 
resulting in a 16-octet (128-bit) reduction in header overhead, 
per address deleted.

NOTE:	The mail server at ietf.org can return the document in

	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.
