This read-create RowStatus object shows and controls the lifecycle state of the single IP-unnumbered configuration row, following the standard RowStatus conventions for creating, activating, or destroying a table entry. An admin sets it to createAndGo when first provisioning IP-unnumbered, or to destroy when removing the configuration entirely. Reading eltIpUnnumberedStatus as active would confirm to the admin that the IP-unnumbered row is fully provisioned and in effect.
