'.' in ethernet device name causes neutron.pp error

[Tom Waterhouse]

I am attempting to install Havana with GRE in a multi-node environment using RDO. My data network device is eth1.1200. I get the following error when the neutron script is being run.

Error: Could not parse for environment production: Syntax error at '.'; expected '}' at /var/tmp/packstack/f8e1377ccde54cb3af8320b1ca559833/manifests/10.93.235.86_neutron.pp:31

I haven't been able to find any information regarding this issue. I believe the offending lines in neutron.pp are:

    if "eth1.1200" {
      $localip = $ipaddress_eth1.1200
    } else {
      $localip = '10.93.235.86'
    }

The dot character in your network device is the problem. Workaround would be to rename your device. Variable $ipaddress_<device> is created by Facter for Puppet. TBH I'm not sure if it is actually created, I would have to test it first. But definitely having dot in variable in Puppet manifest is syntax error [1], so I'm also not sure if this issue can be fixed.
