Hi Guys
As agreed I would share what the LINX’s Juniper SE shared with me with regards to RFC8950.
Hope this is useful info.

Hi Mo,
Hope you’re well.
We support RFC5549 (predecessor to RFC8950) on MX since 17.3R1. Other platforms like QFX had support added later as per below:
https://apps.juniper.net/feature-explorer/feature-info.html?fKey=7931&fn=Re…
Below are some PRs that affected RFC8950 compliance:
PR1649332<https://prsearch.juniper.net/problemreport/PR1649332> : RFC 8950 Extended Nexthop Encoding Capability conformance issue
PR1716946<https://prsearch.juniper.net/problemreport/PR1716946> : BGP connection doesn't establish when it is configured with rfc8950-compliant under logical-systems on all Junos and Junos OS Evolved platforms
From the last PR, the fixes are available in:
22.4R2
22.4R3
23.1R2
23.2R1
23.3R1
Reference documentation:
https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/topic…
For point to point BGP peering, the dynamic tunnels described in above doc are not required.
I tested on 23.1R2 and below is my simple topology and sample config:
LAN01(2.2.2.0/24) ------- ge-0/0/2 - R1 (AS65001) - ge-0/0/1---- v6 Peering ---- ge-0/0/1 R2 (AS65002) ge-0/0/2 ------- LAN02 (1.1.1.0/24)

AS path: 65001 I, validation-state: unverified

Please let me know if you would like to have a quick call to go through.

Hi all,
while requesting lab resources to test RFC8950 with our Nokia boxes, a
colleague hinted me at Containerlabs <https://containerlab.dev/>.
It appears to be a nice solution for testing vendor interoperability
with regard to RFC8950. One can instantiate containers running network
operating systems from various vendors and can easily configure their
topology.
However, I have no experience with that software so far. Is anyone of
you familiar with it and can estimate how well we could make use of it
for our purposes?
Best regards,
Daniel W.
