This value represents the maximum total path cost
allowed from the executor to any node within an area.
The path cost is the sum of the circuit costs along
a path between two nodes. This parameter defines the
point where the executor node's Routing routing
decision algorithm declares another node unreachable
because the cost of the least costly path to the
other node is excessive. For correct operation, this
parameter must not be less than the maximum path cost
of the network.
