Description Scott Schmit 2014-02-25 01:25:51 UTC
Description of problem:
It appears that the latest version of NetworkManager broke automatic IPv6 configuration--I get two routes via ip -6 route: the link local route and a static default route, but no RA-provided network routes.

Attempts to connect via IPv6 to other machines on the local network fail (except connections to the router itself).  Connections via IPv4 work fine.

Version-Release number of selected component (if applicable):
NetworkManager-0.9.9.0-30.git20131003.fc20.x86_64

How reproducible:
100%

Steps to Reproduce:
1. Connect to a network that advertises IPv6 via RA with the network configured with IPv6 fully automatic
2. Attempt to connect to other machines on the local network (not via the router) over IPv6.
3.

Actual results:
Timeouts and failures

Expected results:
Success

Additional info:
I downgraded to NetworkManager-0.9.9.0-20.git20131003.fc20.x86_64 and IPv6 connections now work again.

At first, I thought it was that accept_ra is disabled for my wireless interface, but that behavior is unchanged between both versions.

Sorry for the noise, I can't seem to type.

This may be a dupe of bug 1045118, except that networking worked for me before, but doesn't now.

Please provide a logfile of NM (with DEBUG logging enabled)

Also interesting is the output of `ip addr` and `ip route` and what does radvdump show?

Thank you

I think this is a duplicate of bug 1068632.

It should be fixed.

This now works (to clear the needinfo flag)
