Lab 5 for CSNE Majors

Overview

We will be continuing with the next 3 learning labs from CISCO. These are more involved labs, and will require some reading and research to understand. A great resource is CCENT/CCNA ICND1 Official Exam Certification Guide, Second Edition .

Steps

  1. Log in at: CISCO Lab Login
  2. Launch the Learning lab
  3. Log in again for the lab
  4. For each lab, if you don't have significant experience setting up Cisco egquipment, it is imporant that you watch he video's for each lab. These are about 14-15 minutes each.

1. "Implementing Single-Area OSPFv3"

Reading: Cisco IPv6 Routing: OSPFv3

Overview:

Open Shortest Path First version 3 (OSPFv3) is an IPv4 and IPv6 link-state routing protocol that supports IPv6 and IPv4 unicast address families (AFs).

OSPFv3 is a routing protocol for IPv4 and IPv6. It is a link-state protocol, as opposed to a distance-vector protocol. Think of a link as being an interface on a networking device. A link-state protocol makes its routing decisions based on the states of the links that connect source and destination machines. The state of a link is a description of that interface and its relationship to its neighboring networking devices. The interface information includes the IPv6 prefix of the interface, the network mask, the type of network it is connected to, the devices connected to that network, and so on. This information is propagated in various type of link-state advertisements (LSAs).

A device’s collection of LSA data is stored in a link-state database. The contents of the database, when subjected to the Dijkstra algorithm, result in the creation of the OSPF routing table. The difference between the database and the routing table is that the database contains a complete collection of raw data; the routing table contains a list of shortest paths to known destinations via specific device interface ports.

OSPFv3, which is described in RFC 5340, supports IPv6 and IPv4 unicast AFs.

Questions

  1. Why would someone want to set up a PAT or NAT? What are it's advantages? What are it's disadvantages?
  2. What exactly does a PAT do? What specifically changes in a packet as it passes through the router?
  3. What is the significance of the DHCP lease time?
  4. What is meant by "Overload"?
  5. Why are no PAT entries created when pinging from the router R1 to the intenet.

3. "Connecting to the Main Office"

Reading:

Activity Objective

In this activity, you will configure the serial connection and a static route. After completing this activity, you will be able to meet these objectives:

  • Configure your serial interface to use PPP.
  • Configure a static route to a given IP network, which can be reached via the serial interface.

  1. What is PPP? What is a serial interface?
  2. What is the purpose of a traceroute? How can this be helpful?
  3. What is a gateway of last result
  4. What two devices are being connected via a serial link?
  5. In the last step why did the pping not work the first time, but did work the second time?
  6. Fill out the Implementation Plan below showing all steps:
