Hi,

DNS records should sync automatically. Make sure you have added both nodes as GSLB servers, in GUI and in CLI using bigip_add script.

Also, if you want to sync zonerunner zones, make sure in DNS > Settings > GSLB > General, you enable "Synchronize DNS Zone Files"

Hello Amine,

I have no problem follow this:

both nodes as GSLB servers -> Yes, node have added to a Datacenter and all with Green lights

in CLI using bigip_add script. -> Ok, I have run bigip_add and gtm_add in the standby node without any problem

 

make sure in DNS > Settings > GSLB > General, you enable "Synchronize DNS Zone Files"-> yes and already done...

But the records are still not sync if I just create a new DNS records in zone file of the active node.  I just use zone runner....Both nodes can serve DNS zones successfully with floating ip... Just the zone files are not in sync between nodes .....How can we troubleshoot this out-sync issue? 

Should they sync immediately when the active node being updated, or by how long will it get to update and sync to standby node?

Thanks

Daniel
