Lost connectivity on packstack - VLAN'd interface
Following this guide (https://www.rdoproject.org/Neutron_with_existing_external_network (https://www.rdoproject.org/Neutron_wi...)) on a CentOS 7 all-in-one PackStack configuration.
If I delete br-ex interface and bring back em1 as an Ethernet device on /etc/sysconfig/network-scripts/ifcfg-em1 I can reach the gateway, the network and have Internet access. I think my problem is, I have em1.107 which is a VLAN within my company and I don't know how to make it work, searched tirelessly online for documentation on my issue.
Configuration available at http://pastebin.com/tRYsR7fe
I'm stumped on this one, please help.
