Hello

I am very new to Opeanstack. I need help to right configuration for packstack , I was able to make it work with this

CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=extnet:br-ex

CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth1

CONFIG_NEUTRON_OVS_TUNNEL_IF=

but with this the problem is : it does not allow to make interface as "Enable External" from horizon , the "Enable External" option is missing. So i was looking at documentation, and I am using bellow, but it does not work, as puppet sent error

CONFIG_NEUTRON_OVS_BRIDGE_MAPPINGS=physnet1:br-eth1

CONFIG_NEUTRON_OVS_BRIDGE_IFACES=br-ex:eth1

CONFIG_NEUTRON_OVS_TUNNEL_IF=eth1

[root@node1 ~]# cat  /var/tmp/packstack/20180402-112851-rCDzij/manifests/192.168.1.5_network.pp.log
