Scenario $3$: Creating Routing Table Rules

Here we will use the same network configuration as in Problem $2.$ Three networks $$ Network A$,$ Network B$,$ and Network C $$ are connected to each other with one router between Network A and Network B$,$ and another router between Network B and Network C$.$ The MAC and IPv$4$ addresses of each network adapter are configured as illustrated in the following figure.$$When you are asked to create routing table rules, make sure to specify the Network Destination, Netmask, Gateway, and Interface fields, and explain why each field$$s value has been chosen in your answer. You do not need to include the Metric field, since metric specifics can only be determined with knowledge of the specifics of a computer$$s environment. You may use the titles given in the figure for the network adapter specifications in the routing table.

$7.$ To get started, calculate the network address and subnet mask of all three networks in this scenario. You will need these values to create rules for the computer$$s routing table.

$8.$ Create a routing table for Computer C that has no default route, and that supports sending packets to all hosts $($directly or indirectly$)$ on Network A$,$ Network B$,$ and Network C$.$ A hint is that this routing table will contain three rules.

$9.$ Create a routing table for Computer C that has a default route, and that supports sending packets to all hosts $($directly or indirectly$)$ on Network A$,$ Network B$,$ and Network C$.$ Make sure to remove redundant routes that are not necessary with the presence of a default route.

$10.$ Would you recommend using the routing table in #$8$ or in #$9,$ for Computer C$?$ Explain why.

$11.$ Create a routing table for Router AB which has no default route, which supports communications to all hosts $($directly or indirectly$)$ on Network A$,$ Network B$,$ and Network C$.$ A hint is that this routing table will contain three rules.
