I'm tring to install ONAP with latest vanilla OpenStack. I get to curious when reading the manual (ONAP Installation in Vanilla OpenStack). It describe each ONAP VM has two vNICs in case of nofloat environment.

what is purpose for private network and public network?


regards.

      Daniel Rose Thanks you. I read the Installing and Running the ONAP Demos, public network seems to be for remote access and connection to Gerrit and Nexus repositories on deploying ONAP. If ONAP is deployed completely from HEAT, does ONAP VMs communicate with each other using private network or all network(private/public network)? in other words, does ONAP use private network only during operation?

      1. Daniel Rose

        most talk to each other through the private network. Look for 10.x ips for examples of that

      2. Marco Platania

        I confirm that ONAP components talk to each other (and to demo VNFs) via the private network. The public one is for remote access.

        Daniel Rose,Marco Platania Thanks you for comments (smile)

      This template replicates the environment that we tested in Rackspace and, for this reason, it is currently used to adapt DCAE to vanilla OpenStack. Other templates use floating IPs and have only 1 vNIC.

        if you check out Installing and Running the ONAP Demos you will see there are 2 networks, private and internet. Now you can define 1 nic and a subinterface on each or you can have 2 nics. Marco Platania can answer why we went with 2 vs 1 in this particular template but functionalitywise it shouldn't matter
