    Hello Numan,

    Thanks for your article – we unfortunately have some issues deploying OVN with our tripleO. The stack fails with this error:
    Error: Evaluation Error: Error while evaluating a Function Call, Could not find data item ovn_dbs_vip in any Hiera data file and no default supplied at /etc/puppet/modules/tripleo/manifests/profile/base/neutron/plugins/ml2/ovn.pp:37:18 on node

    I didn’t find any mention of that ovn_dbs_vip, but it apparently should be generated/provisioned by tripleO, according to a chat you had on 2017-06-14[1]

    But apparently, we’re missing something somewhere. Care to explain a bit how the IP is provisioned? That part seems pretty obscure, and we’re unable to tackle that down.

    Small info: we’re deploying ocata (for now – we will move to pike very soon).

    Thank you!
