Re: 31 bit ptp link addressing?

In the referenced message, Adrian Chadd said:

Hi all,

Just (mostly) out of personal curiousity - is anyone here running any PtP links using 31 bit prefixes rather than the /30's we're all happy with?

If you go "huh?" take a look at rfc3021 - "Using 31-Bit Prefixes on IPv4 Point-to-Point Links"

Thanks, Adrian

Yes, and it works wonderfully. The only issue is (for me) getting around the thought that even=low and odd=high, vs the case where odd=low and even=high. For example, when I'm on a router, look at an interface, and want to ping the other end, I have to get out of years of autopilot.
