Host 2, to Fa0/5; Host 3, to Fa0/8.
Step 2: Perform basic configuration on Router 1
Step 3: Configure R1 to support inter-VLAN traffic
The FastEthernet 0/0 interface on R1 will be subinterfaced to route traffic from each of the three VLANs. Each subinterface IP address will become the default gateway for its designated VLAN.
Step 4: Perform basic configuration on Switch 1
Step 5: Create, name, and assign ports to three VLANs on S1
This network contains one VLAN for the server farm and two VLANs for user groups.
Why is it good practice to place the server farm in a separate VLAN?
Step 6: Create the trunk on S1
Enter the following command to establish interface Fa0/1 as a trunk port:
Step 7: Configure the hosts
Configure each host with the proper IP address, subnet mask, and default gateway according to the
addressing table.
Step 8: Verify that the network is functioning
a. From each attached host, ping the other two hosts and each of the router sub-interface IP addresses.
Were the pings successful? Jawaban: yes
If the answer is no, troubleshoot the router, switch and host configurations to find the error.
b. From the switch S1, ping the router default gateway 192.168.1.1.
Were the pings successful? Jawaban: yes
Step 9: Configure, apply, and test an Extended ACL to filter inter-VLAN traffic
Members of the Users1 VLAN should not be able to reach the server farm, but members of the other VLAN should be able to reach each other and the router. Users1 should be able to reach VLANs other than the server farm.
Step 10: Reflection
  1. Why is it good practice to perform and verify basic and VLAN-related configurations before creating and applying an ACL? Jawaban: Problems can be traced to the syntax and placement of the ACL.
  2. What results would have been produced if the ACL had been placed on subinterface FastEthernet 0/0.3 going out and PC2 pinged PC3?Jawaban: Because the ping packets would first be switched to FastEthernet 0/0.4 and then be forwarded out to the PC3, the ACL would have no effect. Pings from PC2 to the servers would succeed.

Step 5: Configure the hosts with IP address, subnet mask, and default gateway
  1. Configure the hosts IP address, subnet mask, and default gateway according to the table and the topology diagram.
  2. Each workstation should be able to ping the attached router. If the pings were not successful, troubleshoot as necessary. Check and verify that the workstation has been assigned a specific IP address and default gateway.
Step 6: Configure dynamic routing on the routers
  1. Configure RIP routing on R1. Advertise the appropriate networks.
  2. Configure RIP routing on R2. Advertise the appropriate networks.
Step 7: Verify connectivity
  1. If the network has converged, list four destinations that H1 should be able to ping: R1, R2, H2, H3, H4
  2. Test connectivity by pinging all the destinations. If any pings fail, troubleshoot the configurations on the routers and host PCs.
  3. Check the routing table on R1.
  4. Verify that all routes appear in the routing table. If a route is missing, troubleshoot the router configuration.
  5. Telnet from the hosts to both routers. All hosts should be able to Telnet to both routers. If Telnet fails, troubleshoot the router and host configurations.

Step 8: Configure and test an ACL that will limit Telnet access
  1. Create a standard ACL that represents the LAN attached to R1. R1(config)#access-list 1 permit 192.168.15.0 0.0.0.255
  2. Now that you have defined the LAN traffic, you must apply it to the vty lines. This allows users from this LAN to Telnet to this router, but will block users from other LANs from accessing Telnet on this router.
  3. Test the restriction.
Step 9: Create vty restrictions for R2
  1. Create a Standard ACL that will not allow hosts on the R1 LAN to Telnet to R2 but will allow hosts on the R2 LAN to Telnet to their attached router.
  2. Conduct the tests to verify that this ACL achieves its goals. If it does not, troubleshoot by viewing the output of a show running-config command to verify that the ACL is present and applied correctly.
Step 10: Reflection
Why is the vty restriction ACL a good practice when configuring a router? Jawaban: if foreign hosts can Telnet into a router, they have the ability to view and modify the configuration. Security demands that Telnet be restricted. Because vty ACLs are applied to the vty lines and not to physical interfaces, this controls Telnet access to the router regardless of from where the host(s) attempt to connect on the network.

  1. Configure a static route on R2 to the R1 192.168.15.0 network. Use the next hop interface on R1 as the path.
Step 8: Configure and test a simple Named Standard ACL
  1. Create a Named ACL that allows H2 to reach other hosts on the local network but does not allow H2 to access remote networks. At the configuration prompt, use this command sequence:
Why do you need the third statement?  Jawaban: To allow other IP traffic not covered by the ACL.
  1. Apply the ACL to the interface.
Describe how you should test this ACL:  Jawaban: Ping from H2 to H1 to verify that H2 can reach hosts on the local network; ping from H2 to R1 and R2. Those pings should fail. Pings from H1 to R1 or R2 should succeed.
  1. Conduct the tests to verify that this ACL achieves its goals. If it does not, troubleshoot by viewing the output of a show running-config command to verify that the ACL is present and applied to the correct interface.
Step 9: Create and test a Named Extended ACL
  1. Create a Named ACL that does not allow H1 to ping R2 but allows H1 to reach the local network and R1. Describe how you would test this ACL:

  2. Add a line to this Named Standard ACL to block H1 from reaching R1, but still permit H1 and H2 to reach each other. Enter configuration commands, one per line. End with CNTL/Z.
If you added a new PC to the topology, attached it to S1, and gave it the IP address 192.168.15.4/24, would it be able to reach R1?Jawaban: Yes
Step 11: Reflection
  1. Why is it good practice to perform basic configurations and verify connectivity before adding ACLs to routers? Jawaban:  ACLs add many possible “error points” or places where a mistake results in traffic being disrupted. It is easier to troubleshoot if you can verify that the basic configuration is working before you add ACLs. If the basic configuration fails after adding an ACL, troubleshoot the ACL.
  2. What advantages do Named ACLs offer? Jawaban: The ability to give ACLs logical, easy-to-remember names; unlimited numbers, rather than being limited to a specific range of numbers.

Tugas CCNA 3 Lab 6.3.2 Configuring OSPF Summarization


Lab 6.3.2 Configuring OSPF Summarization
Step 1: Connect the equipment
  1. Connect Router 1 to Routers 2 and 3 with serial cables. Connect Router 2 to Router 3 with a serial cable.
  2. Connect the Router 2 Fa0/0 interface to the Switch 2 Fa0/1 interface using a straight-through cable.
  3. Connect the Router 3 Fa0/0 interface to the Switch 3 Fa0/1 interface using a straight-through cable.
  4. Connect Host 2 to Switch 2 and Host 3 to Switch 3 to the Fa0/2 interface using straight-through cables.
  5. Connect Host 1 to the Router 1 Fa0/0 interface using a crossover cable.
  6. Connect a PC with a console cable to perform configurations on the routers and switches.
Step 2: Perform basic configurations on the routers
  1. Establish a console session with Router 1 and configure hostname, passwords, and interfaces as shown in the addressing table. Save the configuration.
  2. Establish a console session with Router 2. Configure hostname, passwords, and interfaces according to the addressing table. Save the configuration.
  3. Establish a console session with Router 3. Configure hostname, passwords, and interfaces according to the addressing table. Save the configuration.
Step 3: Perform basic configurations on the switches
  1. Establish a console session with Switch 2 and configure hostname and passwords according to the addressing table. Save the configuration.
  2. Perform a similar configuration on Switch 3, configuring the hostname and passwords as described for SW 2. Save the configuration.
Step 4: Configure the hosts with the proper IP address, subnet mask, and default gateway
  1. Configure each host with the proper IP address, subnet mask, and default gateway for the network on which it resides. Host 1 should be assigned the address 209.165.201.1/24. Host 2 and Host 3 should be assigned IP addresses in the 192.168.10.0/28 and 192.168.10.32/28 networks respectively. All three PCs use the Fa0/0 interface of their attached router as their default gateway.
  2. Each workstation should be able to ping the attached router. If the ping is not successful, troubleshoot as necessary. Check and verify that the workstation has been assigned the correct IP address and default gateway.
Step 5: Configure OSPF routing with default summarization
  1. On Border, configure OSPF as the routing protocol with a process ID of 1 and advertise the appropriate networks.
  2. Perform a similar configuration on R2, using the same process ID and advertising the appropriate networks. Remember to advertise the FastEthernet interface.
  3. On R3, perform a similar configuration, using the same process ID and advertising the appropriate networks.
Step 6: Configure and redistribute a default route for Internet access
  1. From the Border router to Host 1, the host simulating the Internet, create a static route to network 0.0.0.0 0.0.0.0, using the ip route command and the next hop interface. This will forward any unknown-destination address traffic to the PC simulating the Internet by setting a gateway of last resort on the Border router.
  2. Border will advertise this route to the other routers if this command is added to its OSPF configuration.
Border(config)#router ospf 1
Border(config-router)#default-information originate
Step 7: Verify the routing configuration
  1. View the routing table on Border.
  2. View the routing tables on R2 and R3.
How is the pathway for Internet traffic provided in their routing tables? There is a gateway of last resort leading to R3, and the default route shows up as a distributed OSPF route.
Step 8: Verify connectivity
  1. Simulate sending traffic to the Internet by pinging from the host PCs to 209.165.201.1.
Were the pings successful? __________ Yes.
Verify that hosts within the subnetted network can reach each other by pinging between Host 1 and Host 2.
Were the pings successful? __________ Yes.
Step 9: Configure OSPF summarization
  1. Compute a summary route for the corporate subnetworks. The networks have been assigned contiguously:
  2. Configure the summary route in router configuration mode, starting with area 0 range followed by the summary route and its mask.
Step 10: Recheck routing tables to verify the summarization
View the effects of summarization using the following commands: Think about your answers to the previous questions. What advantage do you see in using summarization in this network? Jawaban: This makes the job of the Border router simpler and easier, as it can represent the whole network with one route. The ISP does not care about individual subnets; its job is simply to provide Internet access to the area. Convergence will be improved, as Border will not have to issue updates on every problem on every subnet.
Step 11: Reflection
List three effects of using summarization within an OSPF area? Jawaban: smaller routing table, lower memory and processor requirements, fewer lookups needed.
