Force Manual Reload Secondary Zone [ Edited ]

[#1]

Hi All

I have a DNS zone defined on 7 Servers:

1 External Primary (on a Domain Controller)

3 External Secondary (on a Domain Controller)

3 Grid Secondary (IBX Nios 8.2 VA IB 14xx)

The soa serial is different between them, on ext prim is always higher.

Is it possibile force reload or refresh zone manualy (in order to avoid the refresh period) and close the gap?

In bind was possibile a rndc reload "zone name"

We need to know because in the near feature must rename a infoblox server wich secondary for other zones

Thanks in advance

Hi Fabio,

In your setup, when changes occur on the MS primary DC, it should send out "Notify" messages to the secondary DC and Infoblox.

Once Infoblox receives the Notify, it should perform an SOA query against the MS primary DC and verify the SOA serial#.

If the SOA serial# on MS primary DC is higher, Infoblox should send out an IXFR incremental zone xfer request to the MS primary DC. Whether an incremental IXFR or complete AXFR should then be performed, is completely the decision of the MS primary DC.

Problem/Question:
1. Is the MS primary DC sending out Notify messages? (You can Edit the zone on MS, goto Properties, click on Notify and verify the configuration).

Answer:
1. set dns transfer <zone> [view] will force a zone transfer. [Recommended]

or
2. Edit the zone, disable it, enable it, restart DNS service. [Not recommended]

Hi Thomas
Thanks for the answers!

On MS server the Notify is configured only for 2 infoblox secondary but one missed
This could be the issue's source, but the missing infoblox server, should receive the update from the other two which are in same grid and configured for same zone?

YES and NO.

NO: In-grid replication of DNS data is only applicable from Infoblox Primary DNS-->Grid Master-->Infoblox Grid Secondary servers, who are configured to use grid replication as the zone data replication mechanism over zone transfer and from Infoblox Primary DNS-->Grid Master-->Infoblox Primary DNS in a multi-master configuration.

YES: You can configure one of your Infoblox secondary servers as the "Lead Secondary". The Lead Secondary is then responsible for performing zone transfers with the MS Primary DC and act as the Primary for zone transfers to the remaining Infoblox secondary servers.
