floating ip are simply public ip which are used to do nat 1:1. (internet->public ip -->nat 1:1-> private ip)
(they call them floating, because you can reassign them to another private ip on the fly ..but it's just nat).

This depend which model you want to implement:

1 central gateway (with failover if possible): works with simple layer2 network, vlan network, ovn. 

1 distributed gateway:(same ip/mac on same vmbr on all host, works with ovn dvr, vxlan-ebgp out of the box, and maybe vxlan without bgp but I'm not sure how routing is done from external network)

(personnaly, distributed gateway is more sexy, no spof, no failover)

Sorry, too much information for me. Please can you explain why we need 
a floating IP? I thought we can use a special static IP on each 
virtual bridge, something like:

Requires to block some ARP traffic on the vxlan.
