Bug 1395764

The ctlplane-ip-range and dhcp-provisioning validations no longer error as described in this bug, however there appears to be a syntactic issue with the check-network-gateway validation

This will need a backport once it's merged.

What does this validator check if there is no undercloud.conf? Does it ping 0.0.0.0 ?

Clarification: I was referring to check-network-gateway as an example of one of the validators. The logic in the other validators also needs some explanations, thanks.

Yes, the check-network-gateway uses 0.0.0.0 to ping as a fallback.

The other validations mentioned above use the following default values:

dhcp-provisioning: eth1
ctlplane-iprange: start: 192.0.2.5, end: 192.0.2.24

Marking as verified according to the comments: openstack-tripleo-validations-8.4.1-5.el7ost.noarch
