The log is reported after peer is created and associated to speaker.
Ex.:
#openstack bgp speaker create --ip-version 4 --local-as 65211 --no-advertise-floating-ip-host-routes bgpspeaker
#openstack bgp speaker add network bgpspeaker provider-network
#openstack bgp peer create --peer-ip 100.94.2.2 --remote-as 65200 --auth-type md5 --password cisco bgppeer
#openstack bgp speaker add peer bgpspeaker bgppeer
#openstack bgp dragent add speaker 27f6b5bc-4b0d-466c-957e-34059bd2cc2b bgpspeaker
If you create a BGP peer without password, everything works just fine.
Opesntack version: Ussuri
Deployed using Juju
Distro: Ubuntu Focal Fossa
The environment is a full deployment with all core services running in multi-node.
This looks a lot with the already reported and fixed bug #1592982.
