  • Manipulate HSRP and its parameters

Exam Objectives

The following exam objectives are covered in this lab:

  • N10-007 1.4: Given a scenario, configure the appropriate IP addressing components (Default gateway)
  • N10-007 1.4: Given a scenario, configure the appropriate IP addressing components (Virtual IP)
  • N10-007 2.3: Explain the purposes and use cases for advanced networking devices (Load balancer)

  • N10-007 3.2: Compare and contrast business continuity and disaster recovery concepts (Availability concepts, Load balancing)

Lab Duration

It will take approximately 1 hour to complete this lab.

Exercise 1 - Configuring HSRP

HSRP allows two or more routers to provide backup for each other in the event of a failure. The benefits of HSRP is that if one router goes down, devices on the network will be able to access the default gateway without having to change any of their configurations.

In this exercise, you will configure NYCORE1 and NYCORE2 to function as an HSRP group where one device will function as the backup of the other.

Learning Outcomes

After completing this exercise, you will be able to:

  • Configure HSRP

Exercise 2 - Priority and Pre-emption

As you have seen so far, there is no mechanism in place to define which of the two devices becomes the active router. Whichever device is active remains so until it goes down.

With the priority and pre-emption functionality, it is possible to force HSRP to choose specific devices as the active and standby routers when functioning normally.

Learning Outcomes

After completing this exercise, you will be able to:

  • Manipulate HSRP and its parameters

Exercise 3 - Examining HSRP

In this exercise, you will examine HSRP as it functions in real time and you will get a feel for how quickly the network is restored if there is a failure in one of the default gateways.

Learning Outcomes

After completing this exercise, you will be able to:

This is a summary exercise. There are no learning outcomes in this exercise.
