This read-create VariablePointer specifies the Loop Avoidance instance to which the Ethernet Flow belongs. It is applicable only to a Transparent Flow, where it should point to the relevant ERP instance for pass-through traffic, and should be zeroDotZero for an Access Flow. For example, an administrator points this object at a specific ERP instance so the transparent flow's pass-through traffic is correctly associated with that ring's loop-avoidance logic.
