seen from the wiki, the load balancer only support:<br>

<br>
think about if I have a A-P mode HA<br>
<br>
VIP : 192.168.0.10<br>
<br>
master-1 192.168.0.100 (A)<br>
master-2 192.168.0.101 (P)<br>
<br>
if I want to use VIP to alway connect with master-1(since it is A mode),<br>
only switch to master-2 when master-1 down. what should I do?<br>
any plan to support more algorithms for neutron lbaas?<br>
<br>
BTW, the usage is from heat:<br>
<br>
etcd_pool:<br>
type: OS::Neutron::Pool<br>
properties:<br>
protocol: HTTP<br>
monitors: [{get_resource: etcd_monitor}]<br>
subnet: {get_resource: fixed_subnet}<br>
<b> lb_method: ROUND_ROBIN</b><br>
vip:<br>
protocol_port: 2379<br>
<br>
<br>
<br>
thanks,<br>
