CARP with Dialup interfaces: how to use "Disconnect dialup interfaces"?

[bimbar]

I have a opnsense cluster with PPPoE dialup and I'm struggling to configure dialup failover.

I suspect there are certain limitations on what has to be configured for it to work. Does the parent interface of the PPPoE interface have to have a CARP ip for it to work?

There is the github thread on the feature but I couldn't get it to work with the rather minimal information in there.

Thankful for any pointers.

EDIT: is it correct that the base interface must have a CARP IP? It seems to work now - with a great amount of flapping, but it quietens down after some minutes.

Wondering the same. I got it running with pfSense in HA where the PPPoE was linked to the CARP IP. However, in opnSense, I can't link the PPPoE to the CARP IP as it does not exist after creation.

So do you mind to share your setup in which, although flapping, it seems to work with opnSense?

It seems the base interface must have carp running with a valid carp ip.

Same Problem here.
Any suggestions?
