I hope you to help me with answering question c,d,e and filling the table!

Network Topology C

The topology has changed again with a new LAN added to R2 and a redundant link between R1 and R3. Use the 192.168.10.0/25 network address to provide addresses to the network devices. Also provide an IP address scheme that will accommodate these additional devices. For this topology, assign a subnet to each network.

Step 1: Determine the number of subnets in Network Topology C.

a. How many subnets are there? ___________

b. How many bits should you borrow to create the required number of subnets? _________

c. How many usable host addresses per subnet are in this addressing scheme? ___________

d. What is the new subnet mask in dotted decimal format _________________________

e. How many subnets are available for future use? _______________

Step 2: Record the subnet information.

Fill in the following table with the subnet information:

Subnet Number	Subnet Network Address	Broadcast Address	First Usable Host Address	Last Usable Host Address
