Ah, in that case, you want something like OSPF-MP.  The concept is that
you assign the IP address(es) you want HA for to a "vni0" interface
which isn't associated with any physical interface on the system, and
configure the routing infrastructure to have routes to the address(es)
via each of your connected networks.  This can be done by configuring a
local routing daemon to advertise host routes via each interface, or by
configuring static routes to these addresses on routers that are
directly connected to the attached networks (these routers would then
propagate reachability information for these addresses via whatever
routing protocol they already use).
