Configuring BIG-IP DNS (formerly GTM) (TRG-BIG-DNS-IL)

 

Course Overview

This course gives networking professionals a functional understanding of the BIG-IP DNS system as it is commonly used. The course covers installation, configuration, and management of the BIG-IP DNS system, and includes a combination of lecture, discussion, and hands-on labs.

Who should attend

This course is intended for system and network administrators responsible for installation, setup, configuration, and administration of BIG-IP DNS systems.

Prerequisites

There are no F5-technology-specific prerequisites for this course:

However, completing the following before attending would be very helpful for students with limited BIG-IP administration and configuration experience:

The following web-based courses, although optional, will be very helpful for any student with limited BIG-IP administration and configuration experience:

  • Getting Started with BIG-IP web-based training
  • Getting Started with BIG-IP Global Traffic Manager (GTM) web-based training

The following general network technology knowledge and experience are recommended before attending any F5 Global Training Services instructor-led course:

  • OSI model encapsulation
  • Routing and switching
  • Ethernet and ARP
  • TCP/IP concepts
  • IP addressing and subnetting
  • NAT and private IP addressing
  • Default gateway
  • Network firewalls
  • LAN vs. WAN

The following course-specific knowledge and experience is suggested before attending this course:

  • DNS resolution process
  • Experience configuring DNS content and resolution servers
  • DNSSEC

Course Objectives

  • Provision the BIG-IP system for operation
  • Back up the BIG-IP system configuration for safekeeping
  • Describe how the Domain Name System (DNS) resolves host names into IP addresses
  • Describe how the BIG-IP DNS system can participate in the DNS resolution process
  • Use DNS Express on the BIG-IP DNS system to accelerate DNS resolution
  • Cache DNS query responses on BIG-IP DNS to accelerate DNS resolution
  • Load balance DNS queries to a pool of DNS servers and monitor pool health
  • Configure the key features of the BIG-IP DNS system to perform intelligent DNS resolution
  • Describe the LDNS probes used by BIG-IP DNS to support path-based load balancing
  • Configure a wide IP pool to use a path load balancing method
  • View and confirm DNS resolution behavior using path load balancing methods
  • Use static and dynamic load balancing methods to intelligently resolve DNS queries
  • Use persistence to effectively return one or more clients to the same virtual server on each query
  • Use manual resume to control certain load balancing behavior in the event of an outage
  • Configure and use load balancing decision logs to fine-tune and troubleshoot DNS resolution
  • Configure monitors on the BIG-IP DNS system in support of DNS resolution
  • Configure BIG-IP DNS to participate in the DNSSEC chain of trust
  • Configure limit settings on virtual servers, servers, and wide IP pools to temporarily direct client traffic away from resources that may not be performing at certain thresholds of efficiency
  • Configure iRules on a wide IP to customize intelligent DNS resolution
  • Describe the other wide IP types provided with BIG-IP DNS
  • Configure a BIG-IP DNS sync group
  • Apply all the principles learned throughout the course to configure a BIG-IP DNS system based on hypothetical specifications

Course Content

  • Overview of the Domain Name System and DNS resolution flow through BIG-IP DNS
  • Configuring DNS listeners
  • Accelerating DNS resolution with DNS Express, DNS cache, and DNS server load balancing
  • Intelligent DNS resolution with wide IPs and wide IP pools
  • Using probes and metrics to assist the intelligent DNS resolution process
  • Intelligent DNS load balancing methods
  • Monitoring intelligent DNS resources
  • Logging GSLB load balancing decisions
  • Using DNSSEC
  • Integrating iRules in the DNS resolution process
  • Managing BIG-IP DNS sync groups
