LOGS and symptom:
After I updated the dns config and increase the servial number of master SOA to 17. I got logs below:
zone test.net/IN/localhost_resolver: loaded serial 17
zone test.net/IN/localhost_resolver: sending notifies (serial 17)
client 10.0.0.1#25801: view localhost_resolver: received notify for zone 'test.net'

No logs from Slave.

After two hours:
client 10.0.0.2#52341: view localhost_resolver: transfer of 'test.net/IN': AXFR-style IXFR started
client 10.0.0.2#52341: view localhost_resolver: transfer of 'test.net/IN': AXFR-style IXFR ended
client 10.0.0.2#32990: view localhost_resolver: received notify for zone 'test.net'

And now client updated its config.

My question is why it's not immediately synchronized.


Thank you in advance.

Hi,

You need to add the secondary dns in the master zonefile.
There also some changes you need to do:
Replase @ with the authoritative dns in the SOA RR
Add the A RRs for the 2 NS RRs:
BTW, since you're trying to run an authoritative dns, you don't need the forwarding stuff in both master and slave named.conf

Regards

Thank you for your comment. I have updated the config accordingly, but still not work. the same with before.

I guess you've increased the serial...

No, I didn't update it, should I ?

Of course you should increase the serial on master.
This way it's aware of zone changes, so it then sends notifies to slaves and they get updated accordingly
Read this for more details

Nope, still not working. It's not synchronized immediately.

Ditch the view in both the master and slave and restart bind.
Also enable AXFR logging in both dns servers to watch the logs when updating a zone in master.
Then try again to increase the serial on master and see if it sends notifies to slave to start the AXFR.
