I have read the text you quote.
That text, which should as you say cause no SR processing in node N, is
the exact text which introduces %.1 and 5.2. 5.2 for example is all
about node N inserting a new SRH based on a Transit SID B2. WHich is
not a local address of N nor a SID of N.
I have no idea what SID in section 5 is a Transit SID, or how it can
actually trigger the desired behavior in nodes which, as you say, ignore
the SID.
I presume that the transit SID has to actually be associated with the
node N. But the texxt does not tell me how.
Yours,
Joel

Hi Joel,
Thank you for posting your question on the mailer.
I believe you have missed the second part of that same sentence:
As per [RFC8200], if a node N receives a packet (A, S2)(S3, S2, S1;
SL=2) and S2 is neither a local address nor a local SID of N *then N*
* forwards the packet without inspecting the SRH*.
Cheers,
Pablo

To ampilfy my question, the text in section 5.1 reads:
if a node N receives a packet (A, S2)(S3, S2, S1;
SL=2) and S2 is neither a local address nor a local SID of N
Which clearly reads as describing a case which according to the
segment
routing header (and the 8200 rules) where the neither the SID nor the
SRH will be processed by node N.
