So what is wrong with a /31? We use /30s but if you are short on IP space, look at using /31 rather than /30 links. Cuts your space usage in half.
/31's are only defined for point-to-point links. Ethernet isn't considered PtP in general.. Many devices won't accept a /31 on anything but a PtP WAN media type link. (or not at all).
