Q$1.$ A router has the following CIDR entries in the routing table:

Address$/$Mask

Next Hop

$135\mathrm{.}46\mathrm{.}56\mathrm{.}0/22$

Interface $0$

$135\mathrm{.}46\mathrm{.}60\mathrm{.}0/22$

Interface $1$

$192\mathrm{.}53\mathrm{.}40\mathrm{.}0/23$

Router $1$

Default

Router $2$

For each of the following IP addresses, what does the router do if a packet with that address arrives?

$135\mathrm{.}46\mathrm{.}63\mathrm{.}10$

$135\mathrm{.}46\mathrm{.}57\mathrm{.}14$

$135\mathrm{.}46\mathrm{.}52\mathrm{.}2$

$192\mathrm{.}53\mathrm{.}40\mathrm{.}7$

$192\mathrm{.}53\mathrm{.}56\mathrm{.}7$

Q$2.$ A Large number of consecutive IP address are available starting at $198\mathrm{.}16\mathrm{.}0\mathrm{.}0.$ Suppose four organizations, A$,$ B$,$ C$,$ D request $4000,2000,4000,$ and $8000$ addresses, respectively. For each of these organizations, give:

the first IP address assigned

the last IP address assigned

the mask in the w$.$x$.$y$.$z$/$s notation

Q$3.$ A router R has the following distance$-$vector table:

Destination

Cost

Next hop

A

$2$

R$1$

B

$3$

R$2$

C

$4$

R$1$

D

$5$

R$3$

R now receives the following report from R$1($the cost of the R$$R$1$ link is $1)$:

$,,,.$

Give R$$s updated table after it processes R$1$s report. For each entry, give a brief explanation.
