Replacing an external DNS with F5 GTM

hello,

 

 

I need to make a new implementation of GTM and I'm with some doubts.

 

 

Our client has some domains and some external DNS servers. and Want to disable these external dns, and that the F5 GTM is the only responsible for resolving these domains.

 

 

The procedure for this would be:

 

 

1) export the zone files of the DNS servers

 

2) import these files zones to GTM, with zonerunner

 

3) create a listener, for example with a selfip ip (external)

 

4) Put this ip listener in the configuration on the company that registers domains, as the primary dns

 

 

 

Are these the steps? I have not done an implementation concerning this.

 

If someone can confirm these steps,

 

 

thanks a lot

    thanks, then i will do this steps.

     

     

    but, Just a detail,

     

     

    our customer reported that some zones need to be signed (ipsec).

     

    Any problem with that?

     

    or we can simply export these zones from the dns server and import to F5 gtm with ZoneRunner?

     

     

    thanks a lot

    Yup, you can just import the zones with ZoneRunner.

     

     

    Do you have DNSSEC licensed on your GTM?

     

     

    http://www.f5.com/pdf/deployment-guides/gtm-dnssec-dg.pdf

     

     

    If so, DNSSEC is really easy.

    Nick, i will check, if in their GTM has de adon to DNSSEC.

     

     

    but, about this doc that you passed, i thin this is aplicated when gtm will work together others dns servers.

     

     

    But in our case, there is not another dns servers,. Just GTM. it will replace the dns that work today.

     

     

    there is this manual: http://support.f5.com/kb/en-us/products/big-ip_gtm/manuals/product/gtm_config_10_2/gtm_dnssec.html?sr=23667742

     

    i thin that it is that i can do,,,,, what do you think?

     

     

    but with it, is not just to export and import the zones, that use dnsec, there is some steps to Creating DNSSEC zone-signing and key-signing keys.

     

     

    Am i right?

     

     

    thanks a lot for more informations
