What Are Rules for Route Selection?

Solution

Rule 1: The route with higher priority is preferred. A small value indicates a high priority. If a route cannot be selected using this rule, go to rule 2.

Rule 2: If two routes have the same priority, the route with the higher internal protocol preference is preferred. A small value indicates a high priority. If a route cannot be selected using this rule, go to rule 3.

Rule 3: If two routes have the same priority and belong to the same protocol, the route with the lower-cost value is preferred. If the cost values of two routes are the same, load balancing can be formed. If the number of routes for forming load balancing exceeds the maximum value (such as m) set by the system, the total number of only the first m routes act as the active routes.
