[Rdo-list] HA Overcloud deployment with network isolation in VLAN mode

[Marius Cornea]

Hi Charles,

Thanks for sharing this!

In fact you should be able to pass the vlan ranges parameters in the
network-environment.yaml as well so  you don't need to do manual changes
post deployment:

NeutronBridgeMappings: 'datacentre:br-ex'
NeutronNetworkVLANRanges: 'datacentre:3510:3600'
