Luis Tomas Bolivar 2023-05-26 13:13:38 UTC Doc Text When a VMs associated to a provider network, with disabled port security, try to reach IPs on the provider network not known by OpenStack, there is a flooding issue due to FDB table not learning MACs.

This patch makes use of a new option in ovn [1] to address this issue, enabling the learning of those IPs in the FDB table. There is currently no aging mechanism for that table, so it should be clean up periodically to avoid scaling issues due to it being too big

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