Assuming that no additional configuration parameters are configured other than what is shown, how could you accomplish this task? (Select three. Each option is a complete solution.) a. For the interface connected to the 192.168.12.0/24 subnet , set the OSPF priority to 2. b. Configure a loopback interface IP address of 1.1.1.1. c. Change the IP address on the interface connected to the 192.168.12.0/24 subnet to 192.168.12.1. d. For the router, set its OSPF priority to 2. e. Change the IP address on the interface connected to the 192.168.12.0/24 subnet to 192.168.12.254. f. For the OSPF process, set the router-id to 200.1.1.1. g. For the OSPF process, set the router-id to 172.16.1.1.
