For your average enterprise network, what are the pros and cons for using a /31 mask on point-to-point links with private addressing over the generally accepted practice of using /30? There's really no need for a broadcast address on a P2P, so what does a /31 offer to an enterprise, if anything, if burning a couple more addresses for the network or broadcast addresses is not a concern? I do understand in public IPv4 space with providers how the /31s are attractive for conservation though I haven't run into one yet that required them.
Am I overlooking making anything more difficult with /31s for administration or in the way any typical protocols work over a P2P? With OSPF, it identifies /30 links as P2P, so I don't see how using /31 makes any difference. OSPF is my largest concern.
There's a similar question on /31s, but the answers about impact to routing protocols like OSPF were mostly speculation, and I would like to have a definitive answer.
