You have to configure it as a clone with notifications enabled, then Pacemaker/CRM will send the appropriate operations to the RA to inform it. The only downside really is that all nodes see all the traffic; this is not as efficient as a dedicated load balancer for a large number of nodes, but for 2-4, it's fine. (I've never really analysed where the break-even is.)
