Your diagram would use two CARP interfaces, not just one. One for the external and one for the internal network. Thus, you'd have carp0 (external) and carp1 (internal), both would exchange ads via multicast by default over their underlying physical interfaces. Yes, this is our setup ;) - at least the relevant part of it. > I was under the impression that it should be possible to exchange CARP > advertisements via the dedicated link (--------), though I have to > admit that I haven't actually built such a network yet -- I'm planning > to do that shortly. Maybe others can weigh in? One can use 'carppeer' to not send multicast but unicast. However, I was under the impression one still needs to do peering on the same link as the carp interfaces sit. Can one use the same 'carppeer ded.ica.ted.ip' statement for all carp interfaces altogether (and the other dedicated peer IP on the other)? This would come in handy. -- Stephan A.
