Environment

  • Platform9 Managed OpenStack - All Versions
  • Clarity UI
  • OpenStack CLI

Cause

The VXLAN VNID Range is exhausted – the maximum number of tenant networks has been reached.

Resolution

  1. In Clarity UI, navigate to Networks > Networking Config.
  2. Expand the VXLAN VNID Range – setting it to a high enough value such that there is sufficient capacity for additional tenant networks to be created.

    Note: Each tenant network will allocate 1 VNID.
