Highly-available BMC is not work in NCSI?

I have deployed 2 rack controller in order to manage bmc.
From a security point of view, all BMC IP addresses are internal network addresses.
In the NCSI ,rack controller can not access its own bmc network which may be the cause of the failure.

Could you please check maas logs (rackd.log and regiond.log) for errors/tracebacks when trying to perform the action and paste them?

@maristelsk, did you ever resolve this? i see an outstanding request from a MAAS engineer (post above this one). ever find the problem?
