Network Topology B

The network topology from Part $1$ has expanded to accommodate the addition of router R$3$ and its accompanying network, as illustrated in the following topology. Use the $192\mathrm{.}168\mathrm{.}10\mathrm{.}0/25$ network address to provide addresses to the network devices, and then design a new addressing scheme to support the additional network requirement.

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

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:

$\backslash$table$[[\backslash$table$[[$Subnet$],[$Number$]],\backslash$table$[[$Subnet Network$],[$Address$]],$Broadcast Address,$\backslash$table$[[$First Usable Host$],[$Address$]],\backslash$table$[[$Last Usable Host$],[$Address$]]],[0,,,,],[1,,,,],[2,,,,],[3,,,,],[4,,,,],[5,,,,],[6,,,,],[7,,,,]]$
