The row status. The creation or deletion of a router interface entry
causes creation or deletion of corresponding entries in other Tmnx MIB
tables with the same vRtrID and vRtrIfIndex values, such as the
vRtrIpAddrTable. The router interface is associated to a physical port
interface through the vRtrIfPortID and vRtrIfEncapValue variables. The
RowStatus cannot be SET to 'active' unless vRtrIfName has been
initialized.
