>
> Interior routers employ an anti-looping mechanism that prevents deliveries 
> from passing through the same router twice on its way from origin to 
> destination.  This mechanism does not prevent echo-back on interior-to-edge 
> connections.  A new solution is needed for this.
> On an edge router, a delivery that enters via the uplinked interior router 
> must not be re-forwarded back to the interior.
> On an interior router, a delivery that arrives from an edge router must not 
> be re-forwarded back to that same edge router.
