Can one subnet to include /127 for point to point connections?
That's the equiv of a /31 in IPv4. Do you use /31's for p-t-p links in your IPv4 network(s)?
(Yes, I've used /31's before, but only to represent 2 /32's. And even that was silly.)
We use /31 (v4) and /127 (v6) for internal PtPs in our mostly-vendor-C network with no special tweaks or odd behaviour. YMMV. There was a talk at the Austin NANOG on this. I asked the audience in a straw-poll what their PtP v6 netmask preferences were - resoundingly audience support was for /127's. Chris.
