Task $1$

This task is based on the network with $2$ routers Rx shown in Figure $1\mathrm{.}1.$

IPv$6$ is supported in all three Ethernet$-$based IP networks $1,2$ and $3$ and the Internet. The interfaces in

Figure $1\mathrm{.}1$ are labeled $w1i,r2i,r23,r13,r12,r11,h22$ and $h11.$ The global routing prefix for all three IP

networks $1,2$ and $3$ is $2a05$:$4$:$3$:$\frac{\text{:}}{48}.$ The MAC address of host $1$ is $0$c:$5$a:$27$:$35$:$23$:$45.$ The IPv$6$ prefix

in IP net$1$ is $2$a$05$:$4$:$3$:$7$::$/64.$

a What is the link Local Unicast address of Host $1$ based on the autoconfiguration?

b Which multicast group does Host $1$ join during the autoconfiguration process?

c Which IPv$6$ prefix is distributed by router R$1$ in IP network $1$ via router advertisement?

The IPv$6$ prefixes in the IP networks in Figure $1\mathrm{.}1$ are as follows :

IP network $2$: $2$a$05$:$4$:$3$:$8$::$/64,$ IP network $3$: $2$a$05$:$4$:$3$:$9$::$/64$

d Host $1$ wants to send an IPv$6$ packet to Host $2.$ Which prefix must it choose for the Dst address?

e Host $1$ sends an IPv$6$ packet to web server $1,$ which has the IPv$6$ address

$2$a$01$:$238$:$20$a:$202$:$1075$::$5.$ What are the Src and Dst addresses of the IP packets captured at

the following interfaces?

r$11$:

Src:

Dst:

r$2$i:
