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).

Are the self-IP addresses local addresses?

A server defines a physical system on the network. The zone file for a hint zone specifies an initial tgm of root nameservers for the zone.

Probe using UDP or the traceroute utility. There should be one A record for each IP address of the machine. You also configure the devices to be in an active-standby tuide system configuration. With the ZoneRunner utility, you can:. A virtual server is a combination of IP address and port number that points to a specific resource on the network. For example, a user attempting to conduct on online banking transaction needs to remain with the same set of resources to ensure that the transaction is completed successfully.

The zone file for a forwarding zone contains only information to forward DNS queries to another nameserver on a per-zone or per-domain basis. Using ZoneRunner to configure named. If this is not the case, please contact devcentral f5. You must perform this task from the command-line interface.

Stub Stub zones are similar to secondary zones, except that stub zones contain only the NS records for the zone. About distributed applications A distributed application is a collection of one or more wide IPs, data centers, and links that serve as a single application to a web site visitor.


If the original Statistics Collection server gkide an IP address of I recommend going through the free online GTM training provided by F At an interval specified in the SOA record, secondary zones query the primary zone to check for and obtain updated zone data.

Configuring a distributed application provides several advantages: A related question about the answer: 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. Primary zones are authoritative, that is, they respond to DNS queries for the domain or sub-domain.

Server names are limited to 63 characters. Stub zones are similar to secondary zones, except that stub zones contain only the NS records for the zone. For example, when a user visits a web site, multiple DNS name resolution requests are generated as the user moves from page to page. Please do not provide personal information. A host is a network resource that is not a part of the BIG-IP product family and does not provide load balancing.

Hint The zone file for a hint zone specifies an initial set of root nameservers for the zone. Every zone needs at least one nameserver. Over time, each generation of a key overlaps the previous generation of the key ensuring that GTM can respond to a DNSSEC query even if one generation of a key becomes unavailable. This dependency ensures that a user cannot access a distributed application when a portion of the resources are unavailable.

Configuring virtual server availability to be dependent on the status of other virtual servers Ensure that multiple virtual servers are configured on the server. About wildcard listeners A wildcard listener is a special listener that is assigned an IP address of 0.


You can organize logical network components into groups that represent a business environment.

Link names are limited to 63 characters. The name of the new Prober pool is based on the IP address of the original Statistics Collection server.

New, Pending, or Configurztion. I recommend going through the free online GTM training provided by F5: All of the resources on your network are associated with a data center. If yes, two self-ip addresses, each local to the pair of LTM devices, should be added as well?

The virtual server is now available only when the virtual servers on the dependency list are also available. Perform these steps on both the active and standby systems. A secondary zone responds authoritatively for the zone provided that the zone data is valid. 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. Gttm virtual server status for clusters You can configure virtual server status configyration be dependent only on the timeout value of the monitor associated with the virtual server.

A pool is a collection of virtual servers that can reside on multiple servers.
