Hi Matt,
For patch 9f926a5, the RFE "Add l2pop support for floating ip resources" has been drafted and is under internal reviewing for now. This RFE adds (host, mac_address, floating_ip_address) to l2pop fdb.

1. For non-DVR floating ip resources, the mac_address belongs to router_gateway port which belongs to the router related to the specific floating ip. As following:
             mac_address:  router_gateway port's mac_address --------------------- router -------- floating ip
2. For DVR floating ip resources, the mac_address belongs to floatingip_agent_gateway port which belongs to the router related to the specific floating ip. As following:
             mac_address:  floatingip_agent_gateway port's mac_address -------- router -------- floating ip

I'm wondering in what use case these information will be used to avoid the broadcast in mac learning and ARP resolution . Could you please provide some use cases?

Best Regards,
Xu, Chenjie
