I'm sorry, we discovered too many "you're router might explode TM" bugs in
the recent SURR (again) so nope still don't feel at all comfortable to run
EVPN on Junos in production.
This is our 3rd code upgrade over the years where we're trying to get EVPN
working as its supposed to, but I'm starting to think that Juniper is just
not the right vendor for running EVPN, they will get there eventually, just
not ready, still.
