The maximum-paths limit must not be exceeded as a result of adding the route to a load-sharing “group.”
The next-hop router must be metrically closer to the destination. That is, its metric for the route must be smaller than the local router’s metric. A next-hop router, being closer to the destination, is often referred to as the downstream router.
The metric of the lowest-cost route, when multiplied by the variance, must be greater than the metric of the route to be added.
