So far both machines claim to be master on an active/active
configuration on both assigned VHIDs.
Quick Update: After changing from sending CARP per multicast to
ip-unicast the newer machine is backup on both VHIDs. If the older
machine goes down, the newer machine gets master on both VHIDs, until
the older machine gets up again.
tcpdump shows that CARP traffic flows freely
on the 4.8 machine: "hostname.carp3"
inet 192.168.3.1 255.255.255.0 192.168.3.255 balancing ip-unicast
carppeer 192.168.3.4 carpdev bge0 pass somepass carpnodes

and on the 4.7 machine: "hostname.carp3"
inet 192.168.3.1 255.255.255.0 192.168.3.255 balancing ip-unicast
carppeer 192.168.3.2 carpdev bge0 pass somepass carpnodes
