[c-nsp] Private IP in point to point link on internet

[CiscoNSP List]

Yes - We were going to use /31's for cust eth links, but as Win7 etc dont support them, it made testing the links to a Lappy/PC rather difficult, so had to stick with wasting 2 IP's and use /30


All our Core p-t-p links are /31s though...saves a heap on IP "wastage"

Since the RFC specifies /31 *only* for WANs, I've found that many
ethernet only things have no support for /31. Only router type products
in my experience.
