You can stop the neutron server and run a script which sets this option on each logical router. something like for i in $(ovn-nbctl --bare --columns __uuid list logical_router) do ovn-nbctl set logical_router $i options:always_learn_from_arp_request=false done > In my case, LRs are not bound to any specific compute chassis. > All DGPs are bound on the central set of gateway chassis. > It's central SNAT and FIP. > > I am looking for the possibility to do distributed SNAT and FIP to > avoid central gateway nodes.
