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).

Specifies that the system uses dynamic ratio configurayion when selecting the link. Are the self-IP addresses local addresses? Primary zones are authoritative, that is, they respond to DNS queries for the domain or sub-domain. Things might have changed, but in the current documentation I find the following:. If the original Statistics Collection server had an IP address of Stub zones are similar to secondary zones, except that stub zones contain only the NS records for the zone.

Third-party load balancing systems A third-party load balancing system is any system, other than a BIG-IP system, that supports and manages virtual servers on the network. This table describes the protocols and guidf the big3d agent uses to communicate with an LDNS when collecting path data for the local DNS servers. Flow of probe process.

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. Zone files for a primary zone contain, at minimum, the start of authority SOA and nameserver NS resource records for the zone. I recommend going through the free online GTM training provided by F About servers A server defines a physical system on the network.


To verify that zone transfers are working properly, modify this Linux command and run it on an external computer: A Guidw view is a modification of a nameserver configuration based on the community attempting to access it. Load balancing outbound traffic through links of differing bandwidths Ensure that at least one data center exists in the configuration.

Enabling global traffic configuration synchronization Enable global traffic configuration synchronization options and assign a name to the GTM synchronization group. When you want the BIG-IP system to display statistics that reflect link bandwidth usage, configure duplex billing.

All of the resources on your network are associated with a data center. The SOA record indicates that a nameserver is authoritative for a zone. Cojfiguration third-party host servers A host is a network resource that is not a part of the BIG-IP product family and does not provide load balancing.

When you assign a Prober pool to a data center, by default, the servers in that data center inherit that Prober pool. There should be one A record for each IP address of the machine.

If yes, two self-ip addresses, each local to the pair of LTM devices, should be added as well? The root hint is built into BIND version 9. This virtual server is also the backup resource for requests that originate from the United Gfm. Because these are two distinctly different roles, the virtual server is a pool member in two different pools.


Was this resource helpful in solving your issue? Configuring virtual server status for clusters You can configure virtual server status to be dependent only on the timeout value of the monitor associated with the virtual server.

F5 Networks recommends that you use stub zones only if you have a specific requirement for this functionality. 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.

These statistics reflect only the number of Probe requests and their success or failure. In general, the New and Pending states are temporary. Secondary Zone files for a secondary zone are copies of the principal zone files. The members of a Prober pool perform monitor probes of servers to gather data about f health and performance of confituration resources on the servers. You must be logged in to answer. If you are using NTP, leave this setting at the default value of There must be exactly one SOA record per zone.

A pool is a collection of virtual servers that can reside on multiple servers. Comfiguration best practice is to create four listeners: There are a number of variables related to what you’re asking for.
