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.
[wolfgang@arbol ~]$ ip -6 neigh show
fe80::201:5cff:fe32:7741 dev p32p1 lladdr 00:01:5c:32:77:41 router
REACHABLE
fe80::a60:6eff:fe74:6fe2 dev p34p1 lladdr 08:60:6e:74:6f:e2 router STALE
fe80::20a:cdff:fe21:7513 dev p32p1 router FAILED
fe80::1 dev p34p1 lladdr 44:94:fc:73:cf:43 router STALE

fe80::9221:55ff:fe66:1b5 dev p34p1 lladdr 90:21:55:66:01:b5 STALE
(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
ipv6.
