Part 2: Network Topology B The network topology from Part 1 has expanded to accommodate the addition of router R3 and its accompanying network, as illustrated in the following topology. Use the 192.168.10.0/24 network address to provide addresses to the network devices, and then design a new addressing scheme to support the additional network requirement. PC-A PC-B PC-C S0/o/o so/0/1 S0/0/1 G0/1 so/0/o G0/1 S1 R1 R3 S3 Step 1: Determine the number of subnets in Network Topology A. Please show all work necessary a. Suppose you want to create six (6) subnets. How many bits do you need to borrow to create the required number of subnets? How many usable host addresses per subnet are in this addressing scheme? What is the subnet mask in dotted decimal format? What is the subnet in CIDR format? How many subnets are available for future use? b. c. d. e
