The following errata report has been submitted for RFC9252,
"BGP Overlay Services Based on Segment Routing over IPv6 (SRv6)".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid7652

--------------------------------------
Type: Editorial
Reported by: Ketan Talaulikar <ketant.ietf@gmail.com>

Section: 3.2.1

Original Text
-------------
   Transposition Offset indicates the bit position, and Transposition
   Length indicates the number of bits that are being taken out of the
   SRv6 SID value and encoded in the MPLS Label field.  The bits that
   have been shifted out MUST be set to 0 in the SID value.

Corrected Text
--------------
   Transposition Offset indicates the bit position and Transposition
   Length indicates the number of bits that are being taken out of the
   SRv6 SID value and put into high order bits of MPLS label field. The
   bits that have been shifted out MUST be set to 0 in the SID value.

Notes
-----
This errata reverses an editorial change that was made during the AUTH48 phase and restores the text that came from the WG and IESG review. Refer https://datatracker.ietf.org/doc/html/draft-ietf-bess-srv6-services-15#page-10

This change was made during the AUTH48 since the "high order bits" was already covered under various subsections of Sec 6. However, readers have reported that there are other places in Sec 6 and Sec 5 where transposition also occurs and that the original text was still required.

Instructions:
-------------
This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
can log in to change the status and edit the report, if necessary.
