$($From the midterm study guide$)$ Consider the topology shown in the Figure below.

Denote the three subnets with hosts as Networks A$,$ B$,$ and C$.$ Denote the subnets

without hosts as Networks D$,$ E$,$ and F$.$

a$.$ Assign network addresses to each of these six subnets, with the following

constraints: All addresses must be allocated from $200\mathrm{.}150\mathrm{.}246/23$; Subnet A should

have enough addresses to support $250$ interfaces; Subnet B should have enough

addresses to support $120$ interfaces; and Subnet C should have enough addresses to

support $120$ interfaces. Of course, subnets D$,$ E and F $($interior subnets for routers$)$

should each be able to support two interfaces. For each subnet, the assignment should

take the form a$.$b$.$c$.$d$/$x$.$

b$.$ Using your answer to part $($a$),$ provide the forwarding tables $($using longest prefix

matching$)$ for each of the three routers.

this is the $3$rd time i post the same question, the answers are not given based on the network $(200\mathrm{.}150\mathrm{.}246/23)$

please answer accordingly, give tone address for each of the hosts, give the forwarding tables correctly and explain how you came up with them $,$ and please kindly include the b$.$ part that asks for the longest prefix

this is important
