Overview: Integrating BIG-IP DNS (formerly GTM) with other BIG-IP systems on a Setting Up a BIG-IP DNS Redundant System Configuration. Hi, Does anyone have any example GTM configurations to provide GSLB to LTMs? and reading this guide: Having said that, here are some simple configuration commands via tmsh for configuring a GTM for initial use. Integrating BIG-IP GTM Into a Network with BIG-IP LTM Overview: Configuring how and when GTM saves configuration changes GTM never saves changes to the configuration (manual save required).

Probe using TCP Cisco routers: These records are used for reverse name lookups. F5 Networks recommends configruation you use stub zones only if you have a specific requirement for this configuratioj. The number of listeners you create depends on your network configuration and the destinations to which you want to send specific queries.
Using wildcard characters in wide IPs to minimize maintenance tasks Determine the domain names and aliases for which you want to configure wide IPs. Multiple view configuration, where you want to allow transfers from GTM.
Whenever the local nameserver starts, it queries a root nameserver in the hint zone file to obtain the most recent list of root nameservers. DNS file type Description SOA Start of authority The start of authority resource record, SOA, starts every zone file and indicates that a nameserver is the best source of information for a particular zone.
You can define persistence for the distributed application, ensuring that a user, who accesses the distributed application uses the same resources during a single session.
Because these are two distinctly different roles, the virtual server is a pool c5 in two different pools. The Mail Exchange resource record, MX, defines the mail system s for a given domain.
The root hint is built into BIND version 9. Load balancing outbound traffic through links of differing bandwidths Ensure that at least one data center exists in the configuration. At an interval specified in the SOA record, secondary zones query the primary zone to gude for and obtain updated zone data.
When you assign a Prober pool to a data center, by default, the servers in that data center inherit that Prober pool. Configuring a distributed application provides several advantages: Overlapping generations of a key.

TXT Text The Text resource record, TXT, allows you to supply any string of information, such as the location of a server or any other relevant information that you want available. A wide IP maps a fully-qualified domain name FQDN to one or more pools of virtual servers that host the content of a domain. Configuratoin names are limited to 63 characters.
A secondary zone responds authoritatively for the zone provided that the zone data is valid. When you add condiguration virtual server to a pool, it becomes a pool member. Perform these steps on both the active and standby systems. The big3d agent on the new primary blade must be up and functioning within 90 seconds the timeout value of the BIG-IP monitor.
New, Pending, or Active.

Link names are limited to 63 characters. Defining a link Ensure that at least one data configuragion exists in the configuration. When you want the BIG-IP system to display statistics that reflect link bandwidth usage, configure duplex billing.
Sign Up Login My Support. In the view hierarchy, this view is listed last. About servers A server defines a physical system on the network.
Configuring virtual server availability to be dependent on the status of other virtual servers Ensure that multiple virtual servers are configured on the server. The ZoneRunner utility updates named.

Creating a master DNS zone A master zone is authoritative. A host is a network resource that is not a part of the BIG-IP product family and does not provide load balancing. The Service resource record SRV is a pointer with which an alias for a given service is redirected to another domain.
If all of the members of a Prober pool are marked down, or if a server has no Prober pool assigned, BIG-IP GTM reverts to a default intelligent probing algorithm to gather data about the resources on the server. The big3d agent can now gather and analyze path and metrics information about outbound traffic passing through the router the link represents. You also configure the devices to be in an active-standby redundant system configuration.
Creating a hint zone Hint zones designate configuraiton subset of htm root nameservers list. I recommend going through the free online GTM training provided by F Using views, you can build multiple nameserver conffiguration on the same server, and have those configurations apply dynamically when the request originates from a specified source. Things might have changed, but in the confituration documentation I find the following: Determine the virtual servers upon which you want the availability of a virtual server to be dependent.
About grm and pool members A pool is a collection of virtual servers that can reside on multiple servers. There must be exactly one SOA record per zone.
Are the self-IP addresses local addresses?
