also available for an interface.

Description
Looking at the networking hash for one of my interfaces networking.interfaces.eth0.ip6
returns the link local IPv6 address instead of the global, the one that you can actually connect to
over the internet.
I see no good reason why it should default to the link local address which is useless in about
98% of all cases and not what the user wants. It should never pick a link local address over a
global scope address.
This becomes even more of a problem because it is picking up the correct network6 value.

Looking at
https://github.com/puppetlabs/facter/commit/4f813e102d8b144f8c90517a5475853dd108d97f
this should already be the case but it doesn't appear to be working.

As you can see my ip6 facts are set to something that starts with fe80.

To clarify, this is what ip a s looks like
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state

2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc

3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN
group default qlen 1000
link/ether 04:01:5f:2f:c3:02 brd ff:ff:ff:ff:ff:ff
For the eth0 interface it should not be picking fe80 but 2a03.

Comment by Daniele Sluijters [ 2015/08/19 ]
Are we going to see a 3.0.3 release or should this be retargeted to 3.1.0?
Comment by Michael Smith [ 2015/08/19 ]
We're leaning towards just doing a 3.1.0 release; if that happens, we'll change all the tickets
targeted at 3.0.3.
