Background
This activity allows you to practice a variety of skills including configuring VLANs, PPP with CHAP, static and default routing, using IPv4 and IPv6. Due to the sheer number of graded elements, you can click Check Results and Assessment Items to see if you correctly entered a graded command. Use the cisco and class passwords to access privileged EXEC modes of the CLI for routers and switches.
Requirements
Addressing
The addressing scheme uses the 192.168.1.0/24 address space. Additional address space is available between VLAN 15 and VLAN 1. VLAN 25 needs enough addresses for 50 hosts. Determine the subnet and complete the subnet table below.
VLAN IPv4 Subnet Address Subnet Mask Hosts
1 192.168.1.192 255.255.255.224 20
15 192.168.1.0 255.255.255.128 100
25 50
99 192.168.1.224 255.255.255.224 20
Complete the Addressing Table by assigning the following addresses to VLAN 25:
R2 G0/0.25 - First IPv4 address
PC25 - 2nd IPv4 address
L25 - Last IPv4 address
Configure IPv4 addressing on the necessary end devices.
On R2, create and apply IPv4 and IPv6 addressing to the G0/0.25 subinterface.
VLANs
On S1, create VLAN 86 and name it BlackHole.
Configure S1 ports in static mode with the following requirements:
F0/1 is the native trunk for VLAN 99.
F0/7 - F0/18 as access ports in VLAN 15.
F0/19 - F0/24 as access ports in VLAN 25.
G1/1 - 2 and F0/2 - F0/6 are unused. They should be properly secured and assigned to the BlackHole VLAN.
On R2, configure inter-VLAN routing. VLAN 99 is the native VLAN.
PPP
Configure R1 and R2 to use PPP with CHAP for the shared link. The password for CHAP is cisco.
Routing
On R1, configure IPv4 and IPv6 default routes using the appropriate exit interface.
On R2, configure an IPv6 default route using the appropriate exit interface.
Configure IPv4 OSPF using the following requirements:
Use process ID 1.
Routers R1 and R2 are in area 0.
R1 uses router ID 1.1.1.1.
R2 uses router ID 2.2.2.2.
Advertise specific subnets.
On R1, propagate the IPv4 default route created.
Configure IPv6 OSPF using the following requirements:
Use process ID 1.
Routers R1 and R2 are in area 0.
Configure OSPF on appropriate interfaces on R1 and R2.
R1 uses router ID 1.1.1.1.
R2 uses router ID 2.2.2.2.
Troubleshooting and Explanations
Show screenshots of all configurations.
Show screenshots of all connections. All devices should be able to ping the web server.
Show troubleshooting steps for OSPF and justify how you know it is working with screenshots of each troubleshooting step. For example, how do you know OSPF neighbors are connected properly?
Explain each step.
What is the proper addressing and sub-netting and why?
What are VLANs and why are they helpful?
What is OSPF? What are the different configurations of OSPF and why would you use one over the other? For example, OSPF with multiple areas.
PART 2: Now you try!
Instructions
Open a new / blank Packet Tracer window that does not have any devices
Add the same devices from Part 1 but use your first name and last name as a prefix. For example, if your name is “Amy Smith”, router one will be named: “R1_Amy_Smith”. Router 2 will be named “R2_Amy_Smith” and so on.
Design a new IP address table for all devices using any IP address in the 172.16.0.0/12 prefix range or 172.16.0.0 to 172.31.255.255. All addresses can be IPv4 for simplicity.
Create the similar VLANs from Part 1 but name them with your first name and last name and a department like human resources (HR) and sales. For example, if your name is “Amy Smith” they should be:
F0/1 is the native trunk for VLAN 99.
F0/7 - F0/18 as access ports in VLAN amysmith_HR.
F0/19 - F0/24 as access ports in VLAN amysmith_Sales.
Configure PPP and OSPF with the same configurations as Part 1. You only need to configure IPv4. IPv6 is not necessary.
Configure proper static IP addresses for the ISP router.
Configure the PCs and Web Server from Part 1 with IPv4 addresses.
Troubleshooting and Explanations
Show screenshots of all configurations.
Show screenshots of all connections. All devices should be able to ping the web server and each other consistent with part 1.
Show troubleshooting steps for the VLANs and OSPF.
Justify how you know they are working with screenshots of each troubleshooting step. For example, how do you know OSPF neighbors are connected properly? How can you identify the proper traffic is being sent by OSPF?
