CCNA 4 Skill 2011 – CCNA Exploration: Accessing the WAN Student Skills Based Assessment Lab

CCNA Exploration: Accessing the WAN Student Skills Based Assessment Lab (CCNA 4 Skill 2011)

Topology Diagram

Addressing Table

Learning Objectives
To complete this lab:

  • •    Cable a network according to the topology diagram
  • •    Erase the startup configuration and reload a router to the default state
  • •    Perform basic configuration tasks on a router
  • •    Configure and activate interfaces
  • •    Configure and activate serial interfaces (PPP with CHAP, HDLC, and Frame Relay)
  • •    Configure RIP on all the routers
  • •    Configure basic router security
  • •    Configure ACLs
  • •    Configure basic NAT

Scenario
This lab tests you on the skills and knowledge that you learned in Exploration 4. Use cisco for all passwords in this lab, except for the enable secret password, which is class.
Task 1: Prepare the Network

  • Step 1: Cable a network that is similar to the one in the topology diagram.
  • Step 2: Clear any existing configurations on the routers.

Task 2: Perform Basic Device Configurations
Configure the R1, R2, and R3 routers according to the following guidelines:

  • •    Configure the router hostname.
  • •    Disable DNS lookup.
  • •    Configure an EXEC mode password.
  • •    Configure a message-of-the-day banner.
  • •    Configure a password for console connections.
  • •    Configure synchronous logging.
  • •    Configure a password for vty connections.

Task 3: Configure and Activate Serial and Ethernet Addresses

  • Step 1: Configure interfaces on R1, R2, and R3.
  • Step 2: Verify IP addressing and interfaces.
  • Step 3: Configure the PC1 and PC3 Ethernet interfaces.
  • Step 4: Test connectivity between the PCs and routers.

Task 4: Configure Serial Interfaces

  • Step 1: Configure and verify PPP encapsulation with CHAP authentication between R1 and R2. The password is “cisco”.
  • Step 2: Configure and verify HDLC encapsulation between R2 and R3.
  • Step 3: Configure Frame Relay between R1 and R3.

Task 5: Configure RIP

  • Step 1: Configure RIP on R1, R2, and R3.
  • RIP updates should only be sent on the serial links between the routers. Prevent all other RIP updates on all networks.
  • Step 2: Test connectivity with the ping command.
  • Step 3: Verify the routing table with the appropriate command.

Task 6: Configure Basic Router Security

  • Step 1: Enable a secure Telnet login using a local database on R2.
  • Step 2: Disable unused services and interfaces on R2.
  • Step 3: Confirm that R2 is secured.

Task 7: Configure Access Control Lists

  • Step 1: Allow telnet to R1 and R3 from R2 only.
  • Step 2: Do not allowlHTTP, Telnet, and FTP traffic from the Internet to PC1.
  • Step 3: Do not allow PC1 to receive traffic from the 10.0.0.128 /25 network.
  • Step 4: Verify that PC3 cannot ping PC1, but can ping 10.0.0.1.

Task 8: Configure NAT.

  • Step 1: Configure NAT to allow PC3 to ping PC1.
  • Step 2: Verify that PC3 can reach PC1.

Task 9: Document the Router Configurations
Task 10: Clean Up

Erase the configurations and reload the routers. Disconnect and store the cabling. For PC hosts that are normally connected to other networks, such as the school LAN or to the Internet, reconnect the appropriate cabling and restore the TCP/IP settings.

Thanks

    where is the answers ?

  6. Anonymous / Apr 18 2011 10:00 pm

    This answer doesn't set up frame relay or NAT, it does PPP on all routers

  7. Anonymous / Apr 20 2011 6:22 am

    the answer plz

  8. Anonymous / Apr 21 2011 7:19 pm

    yup. it's missing nat

  9. Anonymous / Apr 22 2011 8:59 pm

    please list the full nat config as well as any other colfig or a link to A compleated packet tracer file

    “This answer doesn't set up frame relay or NAT, it does PPP on all routers”

    can you post the missing command. thanks

  16. LaMa / Apr 28 2011 4:47 am

    http://www.mediafire.com/?db87f3ufrccho69
    without “Enable a secure Telnet login using a local database on R2.”

    thank u so much, LaMa.

    Can you explain to me about commands to configure Frame Relay in your Lab, please ?
