6.4.1 Packet Tracer – Skills Integration Challenge Answers
|Device||Interface||IP Address||Subnet Mask|
- Apply basic router configurations
- Configure dynamic and default routing
- Establish teleworker services
- Test connectivity before ACL configuration
- Apply ACL policies
- Test connectivity after ACL configuration
This activity requires you to configure a default route as well as dynamic routing using RIP version 2. You will also add broadband devices to the network. Finally, you will set up ACLs on two routers to control network traffic. Because Packet Tracer is very specific in how it grades ACLs, you will need to configure the ACL rules in the order given.
Task 1: Apply Basic Router Configurations
Step 1: Configure basic commands.
Using the information in the topology diagram and addressing table, configure the basic device configurations on R1, R2, and R3. Hostnames are configured for you.
Include the following:
- Console and vty lines.
- Disable domain name lookup.
- Interface descriptions.
Task 2: Configure Dynamic and Default Routing
Step 1. Configure default routing.
R2 needs a default route. Use the exit-interface argument in the default route configuration.
Step 2. Configure dynamic routing.
Configure RIPv2 on R1, R2, and R3 for all available networks. R2 needs to pass its default network configuration to the other routers. Also, be sure to use the passive-interface command on all active interfaces not used for routing.
Step 3. Check results.
Your completion percentage should be 59%. If not, click Check Results to see which required components are not yet completed.
Task 3: Establish Teleworker Services
Step 1. Add WAN devices.
Add one DSL and one cable modem according to the topology diagram.
Step 2. Name the WAN devices.
Use the Config tab to change the display name of each WAN device to Cable and DSL, respectively.
Step 3. Connect the WAN devices.
Connect the WAN devices to their PCs and the Internet using the appropriate cables and interfaces.
Step 4. Check results.
Your completion percentage should be 86%. If not, click Check Results to see which required components are not yet completed.
Task 4: Test Connectivity Before ACL Configuration
At this point, all branches of the topology should have connectivity. Switching between Simulation mode and Realtime mode can speed up convergence.
Task 5: Apply ACL Policies
Step 1. Create and apply security policy number 1.
Implement the following ACL rules using ACL number 101:
- Allow hosts on the 192.168.30.0/24 network web access to any destination.
- Allow hosts on the 192.168.30.0/24 network ping access to any destination.
- Deny any other access originating from the network.
Step 2. Create and apply security policy number 2.
Because ISP represents connectivity to the Internet, configure a named ACL called FIREWALL in the following order:
- Allow TW-DSL web access to the Intranet server.
- Allow TW-Cable web access to the Intranet server.
- Allow only inbound ping replies from ISP and any source beyond ISP.
- Allow only established TCP sessions from ISP and any source beyond ISP.
- Explicitly block all other inbound access from ISP and any source beyond ISP.
Step 3. Check results.
Your completion percentage should be 100%. If not, click Check Results to see which required components are not yet completed.
Task 6: Test Connectivity After ACL Configuration
Teleworkers should not be able to ping the Intranet Server, but should be able to access its HTTP server via the web browser. Included in the activity are three PDUs, two of which should fail and one should succeed. Check the Connectivity Tests in the Check Results menu to be sure that the completion results are 100%.
