CCNA 3 Lab 4.2.3.2

Lab 4.2.3.2 Designing and Applying an IP Addressing Scheme

Step 1: Cable the network

a.       Connect Host1 to Switch1 port Fa0/2, using a straight-through Ethernet cable.

b.      Connect Host2 to Switch2 port Fa0/2, using a straight-through Ethernet cable.

c.       Connect Switch1 port Fa0/1 to Router1 port Fa0/0, using a straight-through Ethernet cable.

d.      Connect Switch2 port Fa0/1 to Router1 port Fa0/1, using a straight-through Ethernet cable.

Step 2: Configure the router

a.       Establish a terminal emulation session from either host to Router1.

b.      Configure the router hostname, passwords, interface IP addresses, and subnet mask. Also configure RIP as the routing protocol.

c.       Save the configuration

Step 3: Configure the switches

a.       Establish a terminal emulation session to Switch1 from Host1.

b.      Configure the switch hostname, passwords, interface VLAN 1 IP address, subnet mask, and default gateway on Switch1.

c.       Save the configuration

d.      Establish a terminal emulation session to Switch2 from Host2.

e.       Configure the switch hostname, passwords, interface VLAN 1 IP address, subnet mask, and default gateway on Switch2.

f.       Save the configuration

Step 4: Configure the hosts

a.       Configure Host1 using the IP address, subnet mask, and default gateway from the table.

b.      Configure Host2 using the IP address, subnet mask, and default gateway from the table.

Step 5: Verify connectivity

To verify that the network is set up successfully, ping from Host 1 to Host 2.

Was the ping successful? Ya berhasil

To verify that the network is set up successfully, ping from Host 2 to Host 1.

Was the ping successful? Ya berhasil

If the ping is not successful, verify the connections and configurations again. Check to ensure that all cables are correct and that connections are seated.

Step 6: Reflection

Subnetting allows the addresses in a network range to be split into smaller groups. This lab split the total number of addresses, 256, into smaller groups of equal size.

How many address are in each subnet? 32 alamat

How many total subnets were created? 8 subnet

The subnet mask is 255.255.255.224. How many host bits were “borrowed” for subnetting?

What is the total number of network and subnet bits in each address?

Host bit yang dipinjam adalah: 3

225.255.255.224/27

                                                 11111111. 11111111.11111111.11111111.11100000

Total number network adalah dan bits subnet : 

nnnnnnnn. nnnnnnnn. nnnnnnnn. nnnhhhhh

n = network

h = host

n = network

n = 27 network

2⁵-2= 32-2 = 30 host

 2³= 8 subnet

Jumlah subnet bits = 19
