| Doc Text: |
In RHOSP environments with ML2/OVN or ML2/OVS that have DVR enabled and use VLAN tenant networks, east/west traffic between instances connected to different tenant networks is flooded to the fabric.
+
As a result, packets between those instances reach not only the Compute nodes where those instances run, but also any other overcloud node.
+
This could cause an impact on the network
and it could be a security risk because the fabric sends traffic everywhere.
+
This bug will be fixed in a later FDP release. You do not need to perform a RHOSP update to obtain the FDP fix.
