I remember quite a long time ago being convinced that ONOS & other SDN
projects would change the industry. All the podcasts were suggesting
they would as well... Today, in the context of what was promised, they
seemingly Still Do Nothing
One project I thought was especially interesting was ONOS.... it seemed
to really suggest it would transform Telcos in the Whitebox craze
timeline. As Openflow and such fell off, I remember ONOS pivoting to
SR-TE & PCE... but I haven't heard about it in quite a while.
Is anyone using this in production? The websites seem to still exist.
https://wiki.onosproject.org/https://opennetworking.org/onos/
Just curious.
Warm regards,

I'd be grateful if anyone from OVH (AS16276) or someone with a contact at
OVH peering could ping me off-list. I can't get a response from the
peering-16276(a)ovh.net distro.
Cheers,
Kelly

In case it is useful for anyone else, underlying issue looks to be this:
Cisco CSCws27022: ECN bits being included as part of ECMP hash on IPv6 TCP
flows (Workaround: Do not use ECMP)
Appears to be platform specific, affecting Cisco Catalyst C9K UADP ASIC
(C9500-32C)
Another work-around might be to configure "ip cef load-sharing algorithm
original"
