Had a similar issue awhile back, with duplicate messages due to both pf boxes thinking they were master. The root cause was a lack of MLD support on the switch connecting them. When I rolled back to v4 and IGMP, everything worked fine again. Jussi and I discussed this in an earlier thread: http://marc.info/?l=openbsd-misc&m=131104609321662&w=4 He suggests using carppeer as a possible workaround but I haven't tried that. Swapping in a switch with MLD support stopped the carp flapping for me, and now carp works fine with both v4 and v6 interfaces. dn
