Next-hop IP address:
For a static route to be added to the routing table, the next-hop IP address must be reachable. If it is
not reachable, the route cannot be considered valid and will not be added.
Interface status:
If the interface specified in the static route configuration is down, the route will not be added to the
routing table. The interface must be up and operational for the route to be valid.
Priority and Distance:
While priority and administrative distance affect route selection, they do not prevent a route from
being added to the routing table. Instead, they influence which route is preferred when multiple
routes to the same destination exist.
