Question

Create a subnet plan on paper that shows the following for each subnet:

a. subnet id / mask and layer 3 broadcast address
b. router interface ip address
c. ip addresses to be assigned to computers/devices within the subnet.

Answer 1

To create a subnet plan, you need to determine the subnet ID, subnet mask, layer 3 broadcast address, router interface IP address, and the IP addresses to be assigned to computers/devices within each subnet. Here is an example of a subnet plan for a network with IP address 192.168.0.0/24 divided into four subnets.

Step-by-step explanation:

To create a subnet plan, you need to determine the subnet ID, subnet mask, layer 3 broadcast address, router interface IP address, and the IP addresses to be assigned to computers/devices within each subnet.

For example, let's say you have a network with IP address 192.168.0.0/24 and you want to create four subnets. You can divide the network into four equal subnets, each with a /26 subnet mask.

Here is a possible subnet plan:

1. Subnet 1:

• Subnet ID: 192.168.0.0/26
• Layer 3 Broadcast Address: 192.168.0.63
• Router Interface IP Address: 192.168.0.1
• IP addresses to be assigned: 192.168.0.2 - 192.168.0.62

Subnet 2:

• Subnet ID: 192.168.0.64/26
• Layer 3 Broadcast Address: 192.168.0.127
• Router Interface IP Address: 192.168.0.65
• IP addresses to be assigned: 192.168.0.66 - 192.168.0.126

Subnet 3:

• Subnet ID: 192.168.0.128/26
• Layer 3 Broadcast Address: 192.168.0.191
• Router Interface IP Address: 192.168.0.129
• IP addresses to be assigned: 192.168.0.130 - 192.168.0.190

Subnet 4:

• Subnet ID: 192.168.0.192/26
• Layer 3 Broadcast Address: 192.168.0.255
• Router Interface IP Address: 192.168.0.193
• IP addresses to be assigned: 192.168.0.194 - 192.168.0.254
