return self.__range_cost<EOL>
Getter method for range_cost, mapped from YANG variable /routing_system/ipv6/router/ospf/area/area_range/range_cost (ospf:range-metric)

YANG Description: Used to consolidate and summarize routes at an area boundary.If the cost parameter is specified, it will be used (overriding the computed cost) to generate the summary LSA. If the cost parameter is not specified, then the existing range metric computation max or min cost of routes falling under this range will be used to generate summary LSA.
