IPv6 under f20, f19 and f18 has been rock solid for me this past year.
Now in, the last few days, yum updates have brought some lossage that
requires a periodic reboot to get IPv6 connections to the internet back.
I can't immediately see what the problem is. The outward-facing
interface still has the same IPv6 address it has had for many months.
The ipv6 default route still points out internet-facing interface.
"ip -6 neigh show" shows only STALE and FAILED transactions. Seems like
one of the latest yum updates pooched the neighbor discovery stuff.

(p32p1 is the outside, internet-facing interface, p34p1 is the inside
local lan-facing interface)
Is anyone else seeing this? Surely I'm not the only one running f20 on
