Aijun, Jingrong,
Could the upper-layer header also be ICMP, as in a ICMP Echo message?

Hi Aijun,
Very good catch!
I think the 4.3.1.2 need to be updated !
I would like to propose some text (maybe later today) for RFC8754 4.3.1.2, as
well as some other text in SRv6-PGM section 4.1 (and some related sections) I
have observed about the Upper-layer processing for further discussion.
Thanks
Jingrong

Subject: About the upper layer header processing in RFC8754(SRH)
Hi, Folks:
RFC8754(SRH) section
4.3.1.2(https://tools..ietf.org/html/rfc8754#section-4..3.1.2<https://urldefense.com/v3/__https:/tools.ietf.org/html/rfc8754*section-4.3.1.2__;Iw!!NEt6yMaO-gk!TQj3lWlbJi1xnhmD0skSC1Qbp_vkkYT77iE2zA_6hLItZqr8eZxbW1IoKhFgaBkD$>)
describes the process of upper layer header as the followings:
IF (Upper-layer Header is IPv4 or IPv6) and
local configuration permits {
Perform IPv6 decapsulation
Resubmit the decapsulated packet to the IPv4 or IPv6 module
}
ELSE {
......
}
And in network programming draft section
9.1(https://datatracker.ietf.org/doc/html/draft-ietf-spring-srv6-network-programming-15#section-9.1<https://urldefense.com/v3/__https:/datatracker.ietf.org/doc/html/draft-ietf-spring-srv6-network-programming-15*section-9.1__;Iw!!NEt6yMaO-gk!TQj3lWlbJi1xnhmD0skSC1Qbp_vkkYT77iE2zA_6hLItZqr8eZxbW1IoKiVOq5HR$>),
one new Ethernet Next Header Type(143) is proposed.
Although the detail process of this new next header are described in the
network program draft, does it need to update the section 4.3.1.2 of RFC8754
to reflect the process of new header type(143)?
Best Regards
