Hi again,

If I understand correctly neutron code, we have security group rule
update notified twice:
First with SecurityGroupServerNotifierRpcMixin [1]
Second with ResourcesPushRpcApi [2]

Can someone involved in neutron code confirm that?

It seems that, in OVS agent implementation, [1] is not used (my agent
is not consuming those messages), but neutron server is sending
messages in this exchange.
This is why I have unroutable messages.
