The SRv6 H.Encaps.Red behavior described in [1] is an optimization of the SRv6 H.Encaps behavior [2]. H.Encaps.Red reduces the length of the SRH by excluding the first segment (SID) in the SRH of the pushed IPv6 header. The first SID is only placed in the IPv6 Destination Address field of the pushed IPv6 header. When the SRv6 Policy only contains one SID the SRH is omitted, unless there is an HMAC TLV to be carried.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
