Segment Routing over IPv6 (SRv6) is the instantiation of Segment
Routing (SR) on the IPv6 data plane. This document specifies new
flavors for the SRv6 endpoint behaviors defined in RFC 8986, which
enable the compression of an SRv6 segment list. Such compression
significantly reduces the size of the SRv6 encapsulation needed to
steer packets over long segment lists.

This document updates RFC 8754 by allowing a Segment List entry in
the Segment Routing Header (SRH) to be either an IPv6 address, as
specified in RFC 8754, or a REPLACE-CSID container in packed format,
as specified in this document.

This document is a product of the Source Packet Routing in Networking Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
