I don't much use ipv4 any more if I can avoid it but isn't it normal for
point-to-point links to have a netmask of 255.255.255.255?
Point-to-point links should have a mask of 255.255.255.252. This provides
a Network, Broadcast and two host addresses.
Why? I'm not saying you cannot do this but I don't see what possible
advantage it offers.
The two cases I see are that you want the individual clients connecting
via p-t-p links to be able to talk in which case you probably want
something bigger than a /30 or you don't in which case a /32 is all you
need.
