There is no validation of IP ranges intersections on the Networks tab

[Julia Aranovich]

According to the https://etherpad.openstack.org/p/limitations-of-networking-configuration the following validation cases are not implemented on UI:

* Neutron networking:
  - IP address ranges of all networks (except Internal network) in cluster must not be intersected to each other.
  - Internal network address space must not intersect with external floating IP range.

* Nova networking : items 2, 3 and 5;
  - IP address spaces of all networks in cluster must not be intersected to each other (exception: Floating ranges can be in Public CIDR).
  - IP address ranges inside Public and Floating networks must not be intersected to each other.
  - Public network gateway field must be presented and must not be in any of Public or Floating IP ranges.

This validation is presented now on backend side only (when user clicks Save Settings or Verify Networks button).

Either we need to update https://review.openstack.org/#/c/69371 up to current master or use some other solution. Probably restrictions for networks the same way as for settings?

[Julia Aranovich (jkirnosova)]

I'm convinced that Network tab should be moved to React first.

IMHO IP ranges intersections stuff isn't related to setting restrictions, it can be done as a separate request. https://review.openstack.org/#/c/69371 won't be useful after moving to React.

I also see no validation for Ironic gateway.

1. Need to enable Ironic when you create new environment
2. Open "Networks" tab and click on "Neutron L3" segment
3. Change "Ironic gateway" to 192.168.3.53
4. Click "Save Settings"

Expected result: Error about intersection between "Ironic gateway" and "Ironic IP range" appears

Actual result: No errors, settings saved successfully

Move bug to 'Medium' because it important to add such validations for user

[Vitaly Kramskikh (vkramskikh)]

Nastya, please file another bug for this case. This bug is fo UI change only, your case needs to be fixed also on backend

[Vitaly Kramskikh (vkramskikh)]

The only think which is left uncovered here is absense of range intersection validation between ranges of one network
