I wasn't talking about SRv6... I am talking about SR-MPLS, signaled via
and supported for IPv6, in the IGP.

Yeah, sorry, this was my fault. Gotta have a catchy name.

I found these threads about BGP Prefix-SID decoded needed for Wireshark.
Anyone know what wireshark version fixes this ? I just installed 3.2.6 and
that doesn’t seem to do it

I have described what SR is, not what vendors (for variety of reasons) do with
it, hence “could” ;-)
As a side note - SRoUDP works seamlessly over either v4 or v6.

Be mindful of sketchy (or non-existent) IPv6 support in SR for IS-IS and
OSPF across all vendors.
Mark.
SR could be instantiated with 2 data planes, MPLS and IPv6 - SR-MPLS and SRv6
respectively.
MPLS data plane could be instantiated over either IPv4 or IPv6 (similarly to
LDP6), MPLSoUDP->SRoUDP allows transport of SR-MPLS over IP/UDP(RFC8663) and
could be used to build innovative, end2end arch

Like SR-VXLAN ?
Interesting... I've never heard of SPRINGv4

Out of curiosity - if you are interested in SR, where are you getting your
information from if not IETF (SPRING)?
As for history - we (at Redback) have published 1st draft describing SR-MPLS
data plane in 2003 (LDP control plane).
