Write the command that will display all different ospf route types that are currently known by the router a. show IP route ospf Review questions 9: 1. There are three possible routes for a router to reach destination Network. The first route is from ospf with a metric of 782. The second row is from RIPv2 with a metric of 4. The third is from eigrp with a composite metric of 20514560. Which route will be installed by the router in its routing table? a. B.Eigrp 2.
