| Doc Text: |
RHOSP 17.1.3 now supports a new aging mechanism for MAC addresses learned through the `localnet_learn_fdb` option that is included in Open Virtual Network (OVN) version 23.09. This new aging mechanism consists of two new options, `fdb_age_thhreshold` and `fdb_removal_limit`.
+
The `fdb_age_thhreshold` option enables you to set the maximum time the learned MACs stay in the FDB table (in seconds).
+
The `fdb_removal_limit` option prevents OVN from removing a large number of FDB table entries all at one time.
+
When you use these new options with `localnet_learn_fdb`, you reduce the likelihood of performance and scalability issues caused by the FDB table from growing too big, a problem often experienced in RHOSP environments that have large provider networks.

@Terry, once you enable the aging mechanism you probably have to add the THT support for this as i can only see it in puppet: https://opendev.org/openstack/puppet-neutron/commit/e2b6b6aeea8dff88ae879eedd4adae32bb484ce4 Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory (Red Hat OpenStack Platform 17.1.3 bug fix and enhancement advisory), and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHBA-2024:2741 |
