This read-create object is the standard RowStatus control governing creation and removal of this static route table entry, per its description. Admins use it to formally activate a newly configured static route or to cleanly remove one that's no longer needed, following the standard SNMP row lifecycle. For example, after setting the next-hop and metric for a new static route, an admin sets this RowStatus to createAndGo to install it, or later to destroy to remove it.
