EXAMPLE:
IP address block for this group will be 10.55.0.0/16
We have 6 different subnets (3 LANs, 3 WANs) in homework but we
will create VLSM structure by finding maximum of last two digits of
student’s numbers:
Maximum = 44
We will form a VLSM structure that uses 10.55.0.0/16 IP block which
supports at least 44 subnets. (Hint: Borrow bits from host
portion)

Comp3, Ahmet_S, Ahmet_R’s G0/0 interface). First usable IP address
is assigned to router’s G0/0 interface, second usable IP address is
assigned to switch, last three usable IP addresses is given to
computers in 44. subnet.
Subnet 34 will be Mehmet’s LAN (which includes Comp4,
Comp5, Comp6, Mehmet_S, Mehmet_R’s G0/0 interface). First usable IP
address is assigned to router’s G0/0 interface, second usable IP
address is assigned to switch, last three usable IP addresses is
given to computers in 31. subnet.
Subnet 23 will be Zeynep’s LAN (which includes Comp7,
Comp8, Comp9, Zeynep_S, Zeynep_R’s G0/0 interface). First usable IP
address is assigned to router’s G0/0 interface, second usable IP
address is assigned to switch, last three usable IP addresses is
given to computers in 94. subnet.
To find the WAN’s subnet ID we will use the following rules
(includes students’ numbers): WAN between Ahmet and Mehmet:
RoundUp [(44+34)/2] = 39
The serial IP addresses of routers in this WAN will be first and
second usable IP addresses of Subnet 18.
WAN between Ahmet and Zeynep:
RoundUp [(44+23)/2] = 34
The serial IP addresses of routers in this WAN will be first and
second usable IP addresses of Subnet 49.
WAN between Zeynep and Mehmet:
RoundUp [(23+34)/2] = 29
The serial IP addresses of routers in this WAN will be first and
second usable IP addresses of Subnet 63.
Configuration Instructions:
There will be at least one Addressing Table including all
details (Device name, Interface, IP Address, Subnet Mask, Default
Gateway, Passwords). Each student will configure a switch, a router
and three personal computers.
Assign the device name according to the Addressing Table. (for
ex: Ahmet_R, Ahmet_S, ...)
Disable DNS lookup to prevent routers / switches from attempting
to translate incorrectly entered commands.
Assign your name as the privileged EXEC encrypted password.
(Ahmet or Mehmet or Zeynep)
Assign your name as the console password and enable login.
(Ahmet or Mehmet or Zeynep)
Assign your name as the VTY password and enable login. (Ahmet or
Mehmet or Zeynep)
Create a banner that warns anyone accessing the device that
unauthorized access is
prohibited.
Configure and activate all interfaces on the routers using the
information contained in the
Addressing Table.
Configure the default SVI on switches with the IP addresses
information according to the
Addressing Table.
Configure RIP v2 on each router.
Save the running configuration to the startup configuration
file.
Configure Personal Computers with IP addresses, subnet masks,
default gateways.
Test end‐to‐end connectivity, use ICMP protocol (ping,
traceroute, etc.)
