CCNA ExplorationRouting Protocols and Concepts:Introduction to Routing and Packet Forwarding Ch1 - Packet Tracer Skills Integration Instructions

Objectives

Design and document an addressing scheme based on requirements.

Select appropriate equipment and cable the devices.

Apply a basic configuration to the devices.

Verify full connectivity between all devices in the topology.

Identify layer 2 and layer 3 addresses used to switch packets.

Task 1: Design and document an addressing scheme.

Step 1: Design an addressing scheme.

Based on the network requirements shown in the topology, design an appropriate addressing scheme.

(Note: Remember that the interfaces of network devices are also host IP addresses and are included inthe above addressing requirements.)

Starting with the largest LAN, determine the size of each subnet you will need for the given hostrequirement.

After the addresses have been determined for all the LAN subnets, assign the first availableaddress space to the WAN link between B1 and HQ.

Assign the second available address space to the WAN link between HQ and B2.

Step 2: Document the addressing scheme.

Use the blank spaces on the topology to record the network addresses in dotted-decimal/slashformat.

Use the table provided in the printed instructions to document the IP addresses, subnet masksand default gateway addresses.

For the LANs, assign the first IP address to the router interface. Assign the last IPaddress to the PC

For the WAN links, assign the first IP address to HQ.

Task 2: Select equipment and cable devices.

Step 1: Select the necessary equipment.

Select the remaining devices you will need and add them to the working space inside Packet Tracer. Usethe labels as a guide as to where to place the devices.

Step 2: Finish cabling the devices.

Cable the networks according to the topology taking care that interfaces match your documentation in

Task 1.

Task 3: Apply a basic configuration.

Step 1: Configure the routers.

Using your documentation, configure the routers with basic configurations including addressing. Useciscoas the line passwords and classas the secret password. Use 64000 as the clock rate.



4/69


Step 2: Configure the PCs.

Using your documentation, configure the PCs with an IP address, subnet mask, and default gateway.

Task 4: Test connectivity and examine the configuration.

Step 1: Test connectivity.

RIP routing has already been configured for you. Therefore, you should have end-to-end connectivity.

Can PC1 ping PC2? ________yes



Troubleshoot until pings are successful.

Step 2: Examine the configuration.

Use verification commands to make sure your configurations are complete.

Task 5: Identify layer 2 and layer 3 addresses used to switch packets.

Step 1: Create a simple PDU ping packet

Enter Simulation Mode.

Use the Add Simple PDU button to create a ping from PC1 to PC3.

Change Edit Filters so that only ICMP is simulated.

Step 2: Addresses at PC1

Record the addresses used by PC1 to send the ping packet to B1:

Layer 3 Source: _________________________________________192.168.1.126

Layer 3 Destination: _________________________________________ 192.168.1.222

Layer 2 Source: _________________________________________ 0001.9713.0EDB

Layer 2 Destination: _________________________________________ 0002.1669.A701

Step 3: Addresses at B1

Record the addresses used by B1 to switch the ping packet to HQ:

Layer 3 Source: _________________________________________192.168.1.126


Layer 2 Source: _________________________________________ None

Layer 2 Destination: _________________________________________ 0x8f

Step 4: Addresses at HQ

Record the addresses used by HQ to switch the ping packet to B2:

Layer 3 Source: _________________________________________192.168.1.126


Layer 2 Source: _________________________________________ None

Layer 2 Destination: _________________________________________ 0x8f



5/69


Step 5: Addresses at B2

Record the addresses used by B2 to switch the ping packet to PC3:

Layer 3 Source: _________________________________________192.168.1.126


Layer 2 Source: _________________________________________ 0001.64C5.8501

Layer 2 Destination: _________________________________________ 000D.BDBB.E27C

Configure static and default routing.





The HQ, B1, B2, and B3 routers each have an address space. Subnet the address space based onthe host requirements.

For each address space, assign subnet zero to the Fa0/0 LAN, subnet 1 to the Fa0/1, and so on.


Document the IP addresses and subnet masks. Assign the first IP address to the router interface.

For the WAN links, assign the first IP address to HQ.


Using your documentation, configure the routers with basic configurations including addressing andhostnames. Use ciscoas the line passwords and classas the secret password. Use 64000 as the clock rate.ISP is the DCE in its WAN link to HQ. HQ is the DCE for all other WAN links.

Task 3: Configure static and default rou ting

Configure static and default routing using the exit interface argument.

HQ should have three static routes and one default route.

B1, B2, and B3 should have one default route.

ISP should have seven static routes. This will include the three WAN links between HQ and thebranch routers B1, B2, and B3.


16/69





You should now have end-to-end connectivity. Use ping to test connectivity across the network. Eachrouter should be able to ping all other router interfaces and the Web Server.

Use extended ping to test LAN connectivity to the Web Server. For example, the test the Fa0/0interface on B1, you would do the following:

CCNA ExplorationRouting Protocols and Concepts: RIP version 1 Ch5 - Packet Tracer Skills Integration Instructions

Configure default routes and redistribute through RIP.




Using the topology and the following requirements, design an addressing scheme:

The WAN links between R1 and R2 and their respective ISP routers are already configured. Also,the links between the ISPs and the Web Servers are already configured.

Since RIPv1 is a classful routing protocol, you cannot implement Variable Length Subnet Masks(VLSM). Subnet each regions address space using the following guidelines:

The largest subnet in Region 1s address space is 1,000 hosts. What is the subnet maskyou should use for the 10.1.0.0/16 address space? __________________________

The largest subnet in Region 2s address space is 500 hosts. What is the subnet maskyou should use for the 172.20.0.0/16 address space? __________________________

For the LANs in Region 1, assign subnet 0 to the LAN attached to FastEthernet 0/0 on B1-R1.Continue to assign LANs in sequence. Subnet 1 is assigned to the LAN attached to FastEthernet0/1 on B1-R1; Subnet 2 to FastEthernet 1/0; Subnet 3 to FastEthernet 1/1 and so on.

For the WANs in Region 1, assign the last subnet to the link between R1 and B3-R1, the secondto last subnet to the link between R1 and B2-R1 and the third to the last subnet to link betweenR1 and B1-R1.

Record the Region 1 subnet assignments in the following table:

RouterSubnetNumber

Subnet Address

B1-R1 Fa0/0 0 10.1.0.0

B1-R1 Fa0/1 1 10.1.4.0

Task 5: Configure RIPv1 routing in Region 1 and Region 2.

Configure RIP routing on all regional routers. Remember, the ISP routers are only using static routing.

Task 6: Disable RIP updates on appropriate interfaces.

RIP updates do not need to be sent out all the router interfaces. Disable RIP updates on appropriateinterfaces.

Task 7: Configure default routes and redistribute through RIP.

Determine which routers need a default route. Then configure that router to redistribute the default routeto other routers in the region.

Task 8: Verify full connectivity between all devices in the topology.


You should now have end-to-end connectivity. Use ping to test connectivity across the network.Each router should be able to ping all other router interfaces and both Web Servers.

For the WAN links, assign the first IP address to R1 and R2 for links to each routers perspectiveB1, B2, and B3 routers.


Using your documentation, configure the routers with basic configurations including addressing andhostnames. Use ciscoas the line passwords and classas the secret password. Use 64000 as the clockrate.

Task 3: Configure static routing between ISP routers.

Each ISP router already has two static routes to the other ISP routers directly connected WANs.Implement static routing on each ISP router to insure connectivity between the two regions.

Task 4: Configure RIPv2 routing in Region 1 and static routing Region 2.

Step 1: Configure RIPv2 routing in Region 1.

Configure all routers in Region 1 (R1, B1-R1, B2-R1, and B3-R1) with RIP as the dynamic routingprotocol. In order to fully appreciate the implementation of your VLSM design in a dynamic routingenvironment, add the following two commands to your RIP configurations:

Rout er ( conf i g- r out er ) #version 2

Rout er ( conf i g- r out er ) #no auto-summary

The version 2command enables RIPv2 which includes the sending of subnet mask information in

routing updates. By default, RIPv2 summarizes updates at classful boundaries just like RIPv1. The no

auto-summarycommand disables. These two commands will be fully explained in the next chapter.

Step 2: Configure static routing Region 2.

Region 2 is not using a dynamic routing protocol. Configure the routers with the necessary static anddefault routes to insure full end-to-end connectivity.

R2 should have three static routes and one default route. B1-R2, B2-R2, and B3-R2 should have one default route each.


RIP updates do not need to be sent out all the router interfaces. Disable RIP updates on appropriateinterfaces.

Introduction:

This Packet Tracer Skills Integration Challenge Activity is very similar to the activities you have created inprior chapters. To allow you to better practice your skills, the scenario is slightly different. In this activity,you build a network from the ground up. Starting with a given address space and network requirements,

you must implement a network design that satisfies the specifications. Next, you implement an effectiveRIPv2 routing configuration with static and default routing for Internet access.

Objectives




Test connectivity between directly connected devices.

Configure RIPv2 routing.

Configure static and default routing for Internet access.





Address the LANs in order starting with LAN 1, then LAN 2, etc. Use the first address for therouter interface and the last address for the PC.

The addressing requirements for the LANs are:

o Router B1 interface Fa0/0 supports 60 hosts.

o Router B1 interface Fa0/1 supports 60 hosts.o Router B2 interface Fa0/0 supports 30 hosts.




o Router HQ interface Fa0/0 supports 5 hosts.

o Router HQ interface Fa0/1 supports 5 hosts.

Address the WANs in order starting with WAN 1, then WAN 2, etc. HQ is the first usable addressin all WAN links, with the exception of the link to ISP. For the ISP link, HQ uses the secondusable address.

o WAN 1 is the link between HQ and B1.




Record the network addresses in dotted-decimal/slash format.

Document the IP addresses, subnet masks and default gateway addresses.


38/69




Step 1: Configure the routers.

Using your documentation, configure the routers with basic configurations, including addressing andhostnames. Use ciscoas the line passwords (console and Telnet). Use classas the enable secret

password.

Step 2: Configure the PCs.

Using your documentation, configure the PCs with an IP address, subnet mask, and default gateway.

Task 3: Test connectivity.

Before continuing, make sure that each device can ping its directly connected neighbor.

Task 4: Configure and verify RIPv2 routing.

Step 1: Configure RIPv2.

Configure all devices with RIPv2 routing. In your configuration, make sure you include the following:

Disable automatic summarization.

Stop routing updates on interfaces that are not connected to RIP neighbors.

Set a default route from HQ to ISP using the next-hop IP address.

Configure static routes on the ISP using the outbound interface.

Redistribute default route from HQ.

Step 2: Verify RIPv2.

Use verification commands to check your configuration. All routers should be converged on all the10.2.0.0/24 and 172.17.1.224/28 subnets.

Introduction:

This activity focuses on subnetting skills with VLSM, basic device configurations, RIPv2 routing and static routing.Once you have configured all devices, you will test for end to end connectivity and examine your configuration.

Objectives



Configure static routing between ISP routers.

Configure RIPv2 routing in both regions.Disable RIP updates on appropriate interfaces.

B2-R2 R2 1 172.20.8.4/30

B3-R2 R2 2 172.20.8.8/30



For the WAN links, assign the first IP address to R1 and R2 for links to each routers perspective B1, B2,and B3 routers.

Task 2: App ly a basic configuration.

Using your documentation, configure the routers with basic configurations including addressing and hostnames.Use ciscoas the line passwords and classas the secret password. Use 64000 as the clock rate.

Task 3: Configure static rout ing between ISP routers.

Each ISP router already has two static routes to the other ISP routers directly connected WANs. Implement staticrouting on each ISP router to insure connectivity between the two regions.

Task 4: Configure RIPv2 routing in both regions.

Configure all routers in both regions with RIPv2 as the dynamic routing protocol. Disable automatic

summarization.


RIP updates do not need to be sent out all the router interfaces. Disable RIP updates on appropriate interfaces.

Task 6: Configure default routes and redistribute through RIP.

In Region 1, determine which router needs a default route. Configure a default route on that router andthen configure that router to redistribute the default route to other routers in the region.

In Region 2, determine which router needs a default route. Configure a default route on that router andthen configure that router to redistribute the default route to other routers in the region.

Task 7: Verify full connectivity between all devices in the topology.


You should now have end-to-end connectivity. Use ping to test connectivity across the network. Eachrouter should be able to ping all other router interfaces and both Web Servers.

Step 2: Veri fy EIGRP.


Step 3: Summarize the routes.

Manually summarize routes advertised for the LANs, on all routers except ISP, using an administrativedistance of 5, so that only one route is sent via EIGRP.

NOTE:The current version of Packet Tracer allows the configuration of the summary command.However, the routing tables will still display as if summarization has not been configured. This is a knownbug that will be addressed in a future release.

Task 5: Fine-tune EIGRP.

Step 1: Adjust bandwidth values used to calculate metrics.

The links between the branch routers (B1 to B2 and B2 to B3) are for backup purposes only. Configurethe bandwidth values to 64 kbps so that EIGRP does not equal-cost load across the T1 links to HQ and

the backup links to the neighboring branch router.

Step 2: Adjust hello in tervals for the slower links.

Change the hello intervals for the 64 kbps links to 60 seconds.

Task 6: Configure Static and Default Routing.

Since Packet Tracer does not support redistribution of default routes, all routers except ISP will need adefault route configured.

Task 7: Test Connectivity and Examine the Configuration.

Configure static routing between ISP routers.

Configure EIGRP routing in Region 1 and RIPv2 routing Region 2.

Disable routing updates on appropriate interfaces.

Configure and redistribute default routes.



62/69






The WAN links between R1 and R2 and their respective ISP routers are already configured. Also,the links between the ISPs and the Web Servers are already configured.

The address space for Region 1 is 10.1.0.0/16. Each branch router (B1-R1, B2-R1, and B3-R1)should be allotted address space based on the following requirements. Starting with the largestrequirement, assign address space to each router




Divide the address space for each branch router into four equal subnets. Record the subnets inthe table below.

Optional: On the topology, label each subnet. To save space, use only the last two octets sinceonly these octets change.

Use the table provided in the printed instructions to document the IP addresses and subnetmasks. Assign the first IP address to the router interface.

For the WAN links, assign the first IP address to R1 and R2 for links to each routers perspectiveB1, B2, and B3 routers.

Task 2: Apply a basic con figuration.Using your documentation, configure the routers with basic configurations including addressing. Useciscoas the line passwords and classas the secret password. Use 64000 as the clock rate.

Task 3: Configure static routing between ISP routers.

Each ISP router already has two static routes to the other ISP routers directly connected WANs.Implement static routing on each ISP router to insure connectivity between the two regions.

Task 4: Configure EIGRP routing in Region 1 and RIPv2 routing Region 2.

Step 1: Configure EIGRP routing in Region 1.

Configure all routers in Region 1 (R1, B1-R1, B2-R1, and B3-R1) with EIGRP as the dynamic routingprotocol.

Use 1 as the process ID for EIGRP

Disable automatic summarization

Manually summarize routes advertised by the branch routers to R1 so that only one route is sent(NOTE: The current version of Packet Tracer allows the configuration of the summary command.However, the routing tables will still display as if summarization has not been configured. This is aknown bug that will be addressed in a future release.)

Configure the hello intervals on the branch routers to 30 seconds.

Step 2: Configure RIPv2 routing Region 2.

Configure all routers in Region 2 (R2, B1-R2, B2-R2, and B3-R2) with RIPv2 as the dynamic routingprotocol. Disable automatic summarization.

Task 5: Disable routing updates on appropriate interfaces.

Routing updates do not need to be sent out all the router interfaces. Disable routing updates onappropriate interfaces.

Task 1: Design and document an addressing scheme

Use the 172.16.0.0/16 to create an efficient addressing scheme that meets the following requirements:(Start with the largest network and move to the smallest. Address the WAN link from R5 to R2 first, thenthe link between R4 to R6.)

Hostname Interface Number of Hosts

R2 Fa0/1 1000

R3 Fa0/1 400

R4 Fa0/1 120

R5 Fa0/1 6000

R5 Fa0/0 800

R6 Fa0/1 2000

R6 Fa0/0 500

NOTE: Interface Fa0/0 has been preconfigured on R1, R2, R3, and R4.

Task 2: App ly a basic con figuration.

On each router use the following chart to complete the basic router configurations.Also, be sure toconfigure addressing and hostnames. The first IP for each subnet should be assigned to the routerinterface. (R5 gets the first IP in its link with R2. R4 gets the first IP in its link with R6.)

ConsolePassword

VTYPassword

EnableSecretPassword

Clockrate (ifapplicable)

cisco cisco cisco 56000

Task 3: Configure Single-Area OSPF routing

Step 1:Configure OSPF (process ID 1) routing on each Router.Step 2:Verify that all routes were learned.

Task 4: Fine-tuning OSPF

Step 1: Use the following guidelines to set the OSPF priority::

R1 will never participate in a DR/BDR election. R2 will always become the DR R3 and R4 will both have the same priority of 100. R4 Should always become the BDR

NOTE: ALL PRIORITIES SHOULD BE SET ON FA0/0

Step 2:Use Shutdown/No Shutdown on interfaces to force a BR/DR election.
