Simple Network

Version: 8.2.2

Design a network in Cisco Packet Tracer to connect ACCOUNTS and DELIVERY departments through the following:

• Each department should contain at least two PCs.
• An appropriate number of switches and routers should be used in the network.
• Using the given network 192.168.40.0, all interfaces sould be configured with correct IP addresses, subnet mask and gateways.
• All devices in the network should be connected using appropriate cables.
• Test communication between devices in both ACCOUNTS and DELIVERY departments.

Network Address: 192.168.40.0
Subnets needed: 2

Number of Subnets:

• 2^x = Subnets needed
• 2^x = 2
• 2^1 = 2
• x = 1, we have 1 as the number of ones in the last octet

Subnet Mask:

• 11111111.11111111.11111111.10000000 = /25
• 255.255.255.128 = decimal

Number of Hosts:

• 2^y-2 = Number of Hosts (y is the number of zeros in the last octet)
• 2^7-2 = (Subtract 2 for IP network and broadcast network)
• 128-2 = 126

Subnet Block:

• 256-last decimal of subnet mask = Subnet Block
• 256-128 = 128
• Subnet Number = 0, 128

1st Subnet

• Subnet Mask: 255.255.255.128
• Network Address: 192.168.40.0
• Min: 192.168.40.1 (network +1)
• Max: 192.168.40.126 (broadcast -1)
• Broadcast Address: 192.168.40.127 (0–127 range = 128 addresses)

2nd Subnet

• Subnet Mask: 255.255.255.128
• Network Address: 192.168.40.128 (previous subnet’s broadcast +1)
• Min: 192.168.40.129 (network +1)
• Max: 192.168.40.254 (broadcast -1)
• Broadcast Address: 192.168.40.255 (128–255 range = 128 addresses)
