The configuration does not implement route backup correctly. The 'permanent' keyword in the first command ensures that the route will stay in the routing table even if the interface goes down, meaning it will not failover to the second route. For route backup, two static routes should be configured with different preferences where the primary route has a lower preference and the backup route has a higher preference, which is not evident from the commands provided.
La respuesta es la B Pagina 209 you can configure two static routes with the same destination address/mask but different preferences and next hops to implement backup of forwarding paths. • A backup route is known as a floating route, which is used only when the primary route is unavailable. That is, a floating route is installed in the IP routing table only when the next hop of the primary route is unreachable
The permanent keyword is used in the first command, which means that the route with the next-hop 12.1.1.1 is set to be permanent, and it will not be removed even if the associated interface goes down.
