[MT-AU Public] /31 and /32 subnets

Hi guys, we are looking at ways to redesign our network a bit to be more lean on IPV4 usage as I'm sure a lot of people are probably doing, between all of our POPS and within our core network we have /30's in use as I suppose most people do, however we are starting to run low on IP's and rather than request another allocation which we could easily justify I would rather try and tidy up our network to be more efficient. I was wondering what people's experience has been with Mikrotik using /31 subnets and /32 addresses with the remote end address as the network address ? We mostly run OSPF for our network routing with some BGP on the edge routers, does anybody have any comments on things to be aware of ? Regards Paul
