This paper considers the special case of the robust network design problem where the dominant extreme points of the demand polyhedron have a disjoint support. In this case static and dynamic routing lead to the same optimal solution, both for the splittable and the unspittable case. As a consequence, the robust network design problem with (splittable) dynamic routing is polynomially solvable, whereas it is coNP-Hard in the general case. This result applies to particular instances of the single-source Hose model.
