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.)
