[spring] Question regarding draft-ietf-spring-srv6-srh-compression

[Tal Mizrahi <[e-mail]>]

Dear Authors,

I have a question regarding the following two paragraphs from the
draft (at the bottom of the message).
If I understand the text correctly, if the compressed segment list
fits into a single SID, then the entire compressed list can be encoded
in the DA, and the packet can be sent without an SRH. Note that this
is specifically relevant with the NEXT-C-SID flavor.

I would highly appreciate if you can confirm my understanding.

Thanks,
Tal.


Quoting the relevant text from the draft:

Regardless of how a compressed segment list is produced, it is encoded
in the IPv6 header and optional SRH as described in Section 4.1 and
4.1.1 of [RFC8754]. The text is reproduced below for reference.

A source node steers a packet into an SR Policy. If the SR Policy
results in a Segment List containing a single segment, and there is
no need to add information to the SRH flag or add TLV; the DA is set
to the single Segment List entry, and the SRH MAY be omitted.
