We have IP address range 192.168.0.0 /24

Tasks:

• Divide the subnet to cover all the needs in the topology and use 192.168.1.0 /25 for the interconnections between the routers.
• Use last three IP addresses in each subnet for Router, switch and DHCP server
• Configure the DHCP server to distribute the remaining IP addresses to the clients with the correct configurations. DNS server IP is 100.100.100.3
• All PCs should have access to Web server network-solution.net

Divide 192.168.0.0 /24 to 4 subnets

192.168.0.0 /26     Marketing

Network ID: 192.168.0.0

Broadcast: 192.168.0.63     

R1 IP address 192.168.62 255.255.255.192

Sw1 IP address 192.168.0.61 255.255.255.192

DHCP server 192.168.0.60 255.255.255.192

DHCP pool 192.168.0.1 – 192.168.0.50

Last 10 IP addresses will keep it as a spare for any new server or printer on the subnet

192.168.0.64 /26   IT

192.168.0.128/26   Sales

192.168.0.192/26   Administration

Divide 192.168.1.0 /25 to small subnets to use for interconnection links so we use /30 subnets

192.168.1.0/30    R1 to R2

192.168.1.4/30   R2 to GW

192.168.1.8/30   GW to R4

192.168.1.12/30   R4 to R5 We will use static Routes to route the networks between the routers to reach the Web server and the DNS
