Comment 48 for bug 1337873

@sirswa I tried to reproduce this in my environment - unsuccessfully.

I created a similar config - please take a look at my it for reference: http://paste.ubuntu.com/15129899/
Maybe you could spot a difference that I overlooked.

This could mean that this change may be interfering with something in your system we did not take under consideration.

Could you provide the output of:
service --status-all

and
find /etc/network
(to see what if-*.d scripts are you running).

Thanks!
