Doc Type: Enhancement
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.

@gurpsing we discussed this RFE during the Neutron squad bug triage. This is a RFE that requires prioritization from product management.
Comment 10 Daniel Alvarez Sanchez 2023-08-14 08:46:20 UTC 
@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:
