I Need help with this Question Asap Please within 24 hrs.

Thanks!

Given the diagram below and OSPF properly configured on routers 1 and 2. The network engineer typed two Cisco IOS commands in the Command Line Interface (CLI) back to back and observed the output below. Explain how the cost to the 192.168.1.0/24 route was calculated in OSPF. (15 points)

R2#show ip route

Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP

D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area

* - candidate default,

O 192.168.1.0/24 [110/65] via 192.168.23.1, 00:03:44, Serial0/3/0

O 192.168.2.0/24 [110/65] via 192.168.23.1, 00:03:44, Serial0/3/0

192.168.3.0/24 is variably subnetted, 2 subnets, 2 masks

C 192.168.3.0/24 is directly connected, GigabitEthernet0/0

192.168.23.0/24 is variably subnetted, 2 subnets, 2 masks

C 192.168.23.0/24 is directly connected, Serial0/3/0

Encapsulation HDLC, loopback not set, keepalive set (10 sec) ! ! Removal of unnecessary lines.
