In the past I've always used /30's for PTP connection subnets out of
old habit (i.e. Ethernet that won't take unnumbered) but now I'm
considering switching to /31's in order to stretch my IPv4 space
further. Has anyone else does this? Good? Bad?

Hi
In reference to the discussion about /31 for router links, I d'like to know
what is your experience with IPv6 in this regard.
I use a /126 if possible but have also configured one /64 just for the link
between two routers. This works great but when I think that I'm wasting 2^64 -

Hey guys,
Just to add to the thread, I am helping run the LA/OC Event. We just
started a google group called CRISISTELECOM right now its in alpha
stage; the more expertise we have the better we can discuss how to help
now and for future situations.
Anyone have the Foundry/Brocade CLI reference PDF
they could send me? Brocade feels you should have a
support contract to have a list of commands the
hardware you purchased offers and I'm having difficulty
with a oc12 pos module.
Thanks,

Just to be technically correct:
Even if you could, you wouldn't do that with 1/8 and 2/8: will need to pair
up 2/8 with 3/8!

I am acting as transit for a number of ASNs, and my upstream peers do

I think they support it on point-to-point media only, which seems

unfortunately.

In that case, the fault would lie just as much with the unconditional
