For each writable object in this row that can be configured to
inherit its value from the corresponding object in the
vRtrIpAddrTable, there is bit within vRtrMplsTpInheritance
that controls whether to inherit the operational value of the
object or use the administratively set value.
Non mask bits will always have value of zero.
This object is a bit-mask, with the following objects:
vRtrMplsTpNodeId 0x1
When the bit for an object is set to one, then the object's
administrative and operational value are inherited from the
corresponding object in vRtrIpAddrTable.
When the bit for an object is set to zero, then the object's
administrative and operational value are whatever the DEFVAL
or most recently SET value is.
