Eduardo Olivares 2023-06-14 16:03:42 UTC Doc Text In Red Hat OpenStack Platform (RHOSP) 17.1 environments with ML2/OVN, DVR enabled and using VLAN tenant networks, east/west traffic between VMs connected to different tenant networks is flooded to the fabric. The consequence is that packets between those VMs reach not only the compute nodes where those VMs run, but also any other overcloud node.
This could cause an impact in the network side
and it could be a security risk because the fabric will be sending traffic everywhere.
This bug will be fixed in a later FDP release, so no RHOSP update is needed to obtain it.
