Let’s see how much you’ve learned about routing paths and subnetting! In this activity, you are given a bunch of source and destination IP address pairs. Your task is to route each of these packets from the correct source network to the correct destination network. Step 1: You will be presented 8 source and destination IP address pairs, one at a time, in the table below. Step 2: You will mimic how the packets travel from the source IP address to the destination IP address within the network. Click the network source (the corresponding orange bubble) and click all the networks it needs to use in order to reach the destination network. You will need to click each network in the right order. Step 3: After you’ve selected the source and destination networks, click the “Check” button. Some of these address pairs may not be represented by the networks available. If that’s the case, click the “Source or destination not present” button. If you make a mistake, click the “Reset” button to try again.
The Correct Answer and Explanation is :
To provide the correct answer and explanation, let’s work through this systematically, given the information provided:
Steps to Solve:
- Understand Source and Destination IPs: Review each source and destination IP address pair to determine the corresponding subnet or network they belong to.
- Identify Routing Path: Based on the network topology (as shown in your image or description), determine the shortest path or the correct series of hops for the packet to traverse from the source to the destination network.
- Handle Unrepresented Networks: If a pair’s source or destination network isn’t available in the topology, mark it as “Source or destination not present.”
- Order Matters: Ensure the route clicks follow the logical sequence based on the network layout.
Example Breakdown (Hypothetical):
Assume a network map with subnets (e.g., 192.168.1.0/24, 10.0.0.0/24, etc.) and routers connecting them. If a pair is:
- Source: 192.168.1.5
- Destination: 10.0.0.8
Steps:
- Identify Source Network:
192.168.1.0/24(subnet includes 192.168.1.5). - Identify Destination Network:
10.0.0.0/24(subnet includes 10.0.0.8). - Trace the Path: Based on the network map, select routers and intermediary networks (e.g., via 192.168.2.0/24 if that connects them).
Explanation (Generalized for 300 Words):
Routing packets involves determining the path from a source network to a destination network using IP addressing and subnetting principles. Subnetting divides a large network into smaller, manageable subnets, defined by their network ID (e.g., 192.168.1.0/24).
For each source-destination pair, the first step is identifying which subnet each IP belongs to. This is done by matching the IP against the subnet’s range using the subnet mask. Once both networks are identified, the routing table or network topology determines the route the packet should take. Routing relies on metrics like the number of hops, link cost, or other predefined criteria to choose the best path.
If a source or destination isn’t present in the network, it implies the subnet isn’t part of the current topology. Mark those cases as “Source or destination not present.”
In practice, routers use ARP (Address Resolution Protocol) and routing tables to direct packets to their next hop. By clicking each network in sequence, you mimic how real-world routers forward packets through intermediary networks toward their final destination.
If you provide more specifics from the network topology or pairs, I can detail the exact sequence for each pair!
