This 2-day course gives networking professionals a functional understanding of the BIG-IP DNS system as it is commonly used. 

The course covers configuration and ongoing management of the BIG-IP DNS system, and includes a combination of lecture, discussion, and hands-on labs.

Course Topics

• 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


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

Skills Gained

Upon successful completion of this course, the student will be able to: 

• 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 DNS resolution with wide IPs and wide IP pools

• Describe how the BIG-IP DNS system can participate in the DNS resolution process

• 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

Thinking about Onsite?

If you need training for 3 or more people, you should ask us about onsite training. Putting aside the obvious location benefit, content can be customised to better meet your business objectives and more can be covered than in a public classroom. Its a cost effective option. One on one training can be delivered too, at reasonable rates.
