Practice Skills Assessment – Packet Tracer

A few things to keep in mind while completing this activity:

  1. Do not use the browser Back button or close or reload any exam windows during the exam.
  2. Do not close Packet Tracer when you are done. It will close automatically.
  3. Click the Submit Assessment button in the browser window to submit your work.

Introduction

In this practice skills assessment, you will configure the Small Business network with NTP, SNMP, EIGRP, PPP CHAP, Frame Relay, dynamic NAT, static NAT, PAT and a GRE tunnel.

Some values that are required to complete the configurations may not have been given to you. In that case, create the values that you need to complete the requirements.

For the sake of time, many repetitive, but important, configuration tasks have been omitted from this assessment. Many of these tasks, especially those related to security, are essential elements of a network configuration. The intent of this activity is not to diminish the importance of full device configurations.

You will practice and be assessed on the following skills:

  • Configuration of NTP
  • Configuration of SNMP and Syslog
  • Configuration of interface addressing and basic settings
  • Configuration of HDLC
  • Configuration of Frame Relay
  • Configuration of PPP
  • Configuration of CHAP
  • Configuration of a GRE tunnel
  • Configuration of static and dynamic routing
  • Configuration of dynamic NAT
  • Configuration of static NAT
  • Configuration of PAT

You are required to configure the devices as follows:

Office-1:

  • Configure HDLC.
  • Configure EIGRP.
  • Configure passive interfaces.

R2:

  • Configure PPP and CHAP authentication on the appropriate interface.
  • Configure EIGRP.
  • Configure static NAT for outside access to an internal server.
  • Configure dynamic NAT.
  • Configure PAT.

R3:

  • Enable time stamps for use with NTP and SNMP logging.
  • Configure the router to use NTP services.
  • Configure logging to the IT Monitor Server.
  • Configure PPP and CHAP authentication on the appropriate interface.
  • Configure Frame Relay.
  • Configure a GRE tunnel.
  • Configure EIGRP.
  • Configure passive interfaces.

Office-2-Branch:

  • Configure Frame Relay.
  • Configure a GRE tunnel.
  • Configure EIGRP.
  • Configure passive Interfaces.

Tables

In some cases, specific interface addresses have been provided to you. You must use them in your configurations. In other cases, when a network is specified instead of a specific address, you can use any address in the network.

You do not configure LAN addresses in this activity. The addresses of the LAN interfaces are provided in this table for reference purposes only.

Instructions

All configurations must be performed through a direct terminal connection to the device console from an available host.

Step 1: Configure NTP, SNMP, and Syslog settings on R3.

a. Configure NTP.

  • Configure R3 to use IT Monitor Server as its NTP server.
  • Use a key value of 15.

b. Configure SNMP.

  • Use an SNMP community string of CiscoPTSA.
  • Allow the SNMP management station only read only rights.

c. Configure Syslog.

  • Configure R3 to use time stamps when logging. The timestamps should include milliseconds.
  • Configure Syslog to send log entries to the IT Monitor Server.
  • Set the message trapping for Syslog to the debugging level.

Step 2: Configure Frame Relay between R3 and Office-2-Branch.

Configure Frame Relay on the interfaces connecting R3 and Office-2-Branchusing the information from the Addressing Table.  You must use the exact addresses specified in the addressing table for the configuration.

Step 3:  Configure a GRE Tunnel between R3 and Office-2-Branch.

  • Configure a GRE tunnel using Tunnel interface 0 on R3 to Office-2-Branch using information from the addressing table.
  • Configure a GRE tunnel using Tunnel interface 0 on Office-2-Branchto R3 using information from the addressing table.
  • You must use the exact addresses specified in the addressing table for this configuration.

Step 4: Configure DCE interfaces.

Configure the DCE interfaces of R2 with a clock rate of 128000.

Step 5:  Configure PPP and CHAP between R2 and R3.

  • Configure interface addressing according to information provided in the Addressing Table. You can use any address in the network specified in the Addressing Table for this configuration.
  • Authenticate the PPP connection with CHAP on both ends of the link.
  • Use the password of PTSAchap.

Step 6:  Configure HDLC on Office-1 and  R2.

It has been decided to remove an earlier PPP configuration from the link between Office-1 and R2.

  • Configure this link with HDLC.
  • Configure interface addressing according to information provided in the Addressing Table. You can use any address in the network specified in the Addressing Table.

Step 7:  Configure NAT on R2.

All hosts should use translated addresses to access destinations outside of the Small Business network.

a. Configure static NAT.

  • Configure static NAT for the IP address of the Partner Server.
  • Use the last host address in the interface S0/1/0 subnet.

b. Configure dynamic NAT.

  • Configure dynamic NAT for all host IP addresses on the LAN network connected to Office-1.
  • Use DYNAMIC as the name for the pool.
  • Use the third through tenth IP addresses that are available on the R2 S0/1/0 subnet.
  • Configure ACL 1 to allow all host IP addresses in Office-1 LAN network to use this group of addresses.
  • Your ACL should have one statement.

c. Configure PAT.

  • Configure PAT to enable the hosts attached to the R3 and Office-2-Branch LANs to access the Internet.
  • Use the interface keyword in the NAT statement.
  • Use ACL 2 to allow all host addresses on both LAN networks to use the overload address.
  • Your ACL should have two statements.
  • Configure all interfaces on R2 as appropriate.

Step 8:  Configure static and dynamic routing.

a. Configure dynamic routing.

  • Configure EIGRP for all networks connected to Office-1, R2,R3, and Office-2-Branch.
  • Use ASN 1.
  • Use the precise inverse masks for all networks.
  • Disable automatic summarization on all routers.
  • Disable EIGRP updates from being sent on the appropriate interfaces. You must do this for each individual interface. Donot use the default keyword with the command.

b. Configure a redistribute a default route.

  • Create a directly attached default route to the Internet on R2.
  • Configure EIGRP to redistribute the default route to the other routers.

      Everyone has to be careful with the router’s names. In my case some names were different. You gave the equivalences below:

      R3-Branch // Office-2-Branch

      Is correct, but you just forgot to add a route to eigrp routing in R3:
      eigrp router 1

      Why would you use “frame-relay map ip 10.10.10.1 202 broadcast”
      It works fine in my config without it. What I did is configure the sublinks (DLCI) in the Frame Relay cloud.

    The problem I’m having with the practice skills assessment is conceptual. I’m not having any trouble giving it the commands it wants for a full score.

    1. Why are we advertising the Frame-Relay network when we have configured a GRE tunnel? Traffic will not be encapsulated unless EIGRP routes through the Tunnel interface. Its actually quite stupid the configuration that the skills assessment requires. The requirements for routing on the R3 and R3-Branch routers are to advertise both the tunnel and the frame-relay network on R3 Branch but only the frame-relay interface is advertised on R3. So no adjacency is even formed through the tunnel. You have a tunnel that will never be used to encapsulate traffic with the exception of traffic actually addressed to the tunnel endpoint interfaces themselves. And sure, GRE is pointless without IPsec encryption but we’ll need to eventually route through a tunnel.

    2. So yeah, we need to form the adjacency through the tunnel to get encapsulated traffic. If we create 2 adjacencies through the tunnel and the frame-relay network, the ip route table prefers the unencapsulated frame-relay route for routing. What we really need is just 1 adjacency and only through the tunnel interface. If we attempt to do so, it works fine UNTIL we use the “redistribute static” command on R2 to redistribute the default route. This causes the tunnel interface on R3-Branch to become disabled as such:

    %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to up

    %DUAL-5-NBRCHANGE: IP-EIGRP 1: Neighbor 10.10.10.1 (Tunnel0) is up: new adjacency
    %ADJ-5-PARENT: Midchain parent maintenance for IP midchain out of 0 65E900C0 – looped chain attempting to stack
    %TUN-5-RECURDOWN: 0 temporarily disabled due to recursive routing

    %LINEPROTO-5-UPDOWN: Line protocol on Interface Tunnel0, changed state to down

    %DUAL-5-NBRCHANGE: IP-EIGRP 1: Neighbor 10.10.10.1 (Tunnel0) is down: interface down

    So I don’t really understand what is causing recursive routing here. Is this a packet tracer glitch? Several google searches give me nothing that applies to this scenario.

    Had a similar problem today with a flapping tunnel interface.
    It turned out to be a recursive routing problem over the tunnel interfaces. In order to fix this, make sure your tunnel destination and source are not learned via EIGRP.
    I removed network statement: network 10.10.10.0 0.0.0.3 on both R3 and R3 branch and my tunnel interface stopped flapping.
    Rather than forming EIGRP neighbourship via the tunnel interface (as per Student Lab Manual) I used frame-relay network 10.10.2.0 0.0.0.3 to form the adjacency.
    After that everything worked flawlessly!!! Nevertheless my final score was 93% for omitting the above described network statement which caused a flapping tunnel interface 😛
    I guess had I left it flapping I would have gotten 100% lol:D

    May 5, 2015
  21. Mr.T

    Amendment to my previous comment:
    In order to get 100% make sure you do advertise the tunnel network on R3-branch only rather than omitting it on both R3 and R3 branch like I did it above:P
    EIGRP adjacency should be created via frame-relay network 10.10.2.0 and tunnel network should only be advertised on R3-branch. This will prevent from creating loops!
