I am installing Fuel-OPNFV Arno and I have a couple of questions. If anyone can give me some information, it would be great. (1) Should "public network" have internet accessibility? What is the purpose of public network? Why do we need public network for OPNFV? (2) NTP server and DNS server are mandatory to install OPNFV? Is it ok to install them on the same computer with Fuel master or Should I do it on separate computer?

Thank you in advance for your help,

Kim

Hi,

I think its not mandatory to have internet access for public networks. you can still install Arno without internet access for public network using the latest release (SR1). Public network is used to access your Horizon dashboard (from external environment) and also a gateway network for accessing your instances in the private network. Someone please correct me if am wrong...

Public Network provides the Front END (routable IPs) to your OPenstack Controllers - as well this provides the range to be used for Neutron Floating IP associations (if you want to provide connectivity through neutron to your VMs) that is the purpose for PUBLIC networking (you can also review the Openstack Networking DOcument ( openstack.org ) for more description on the base networks.

NTP Server is mandatory and must be accessible by all nodes - you cannot use the FUEL server as NTP natively, you should provide a NTP that is routable to all your nodes. DNS is required if you are using internet repos, not so important if you are using the local mirror provided in SR1

For your last question - is it ok to install them on the same computer with FUEL master - if you mean, that you will setup a VM or something running DNS and NTP - so long as they are on a different IP it doesnt really matter "which physical machine" they run in. So long as the networking is valid.
