Don't really see the reasoning behind this, normally you'd want the
service to be available if any of the paths is still reachable.

To prevent what I would call undefined behavior, you would be better
off with just one ring if you don't want redundancy.

Otherwise look into setting up ping location restrictions (but this is
done one layer up, in the resource manager, not in the communications
layer). See http://www.clusterlabs.org/wiki/Pingd_with_resources_on_different_networks

Now given the statement made here, I have to ask, if they're not
redundant, why use two multicast groups?
