| Doc Text: |
Before this update, a flooding issue occurred when an instance, associated with a provider network with disabled port security, attempted to reach IPs on the provider network that were not recognized by OpenStack. This flooding occurred because the forwarding database (FDB) table was not learning MAC addresses. This update uses a new option in OVN to enable the learning of IPs in the FDB table. There is currently no aging mechanism for the FDB table. But you can clean up the FDB table periodically, to prevent the occurrence of scaling issues caused by the size of this table.
