Some writable object in this row that can be configured to inherit its value from its corresponding object in the vRtrLdpNgGeneralTable. vRtrLdpIfInheritance controls whether to inherit the operational value of that object, or use the administratively set value. Non mask bits will always have value of zero, and any attempt to change the value will be silently discarded. When the bit for an object has value of one, then the object's administrative and operational value are whatever the DEFVAL or most recently SET value. The mask bit(s) will be set to one when set is performed on the inherited object(s). Any attempt to set the mask bit to one will be silently discarded. When the bit for an object is set to zero, then the object's administrative and operational value are inherited from the corresponding object in vRtrLdpNgGeneralTable. This object is a bit-mask, with the following positions: vRtrLdpNgInetIfKAFactor 0x1 vRtrLdpNgInetIfKATimeout 0x2 vRtrLdpNgInetIfHelloFactor 0x4 vRtrLdpNgInetIfHelloTimeout 0x8 vRtrLdpNgInetIfTransAddrType 0x10
