The slave should start working again once it discovers that the master has become reachable. According to the circumstances, this moment may differ, either grossly or subtly, from the moment when the master actually becomes reachable. For example, if the master itself has failed, been recovered, and been restarted, it will likely send NOTIFY messages to the slaves, which will then be aware of restored reachability, and will be able to resume service directly. On the other hand, if the reachability failure is due to a network fault, the master will have continued running, and will have no reason to send NOTIFY on restoration of reachability. In this case, resumption of normal service will depend on how the slave server software implements recovery from an expiry event. I expect, but have never had occasion to confirm, that this would depend on the REFRESH and RETRY timers. this might involve a delay of some, or even many, hours. In any recovery situation, I would be minded to check slave status within a few minutes of restoration of reachability, and to force the master to send NOTIFY messages in case any slaves had not yet resumed service.

No. The slave will try every REFRESH interval to see if it can contact the master.

There's no functionality in BIND that would keep sending notices to slaves when they are down.

What if the link is failed between master/slave
Hi There, I have bind Master server with me and slave is at other remote location. My query is since I have opted for PUSH update from master to slave over random port. What if the link at slave is down and NOTFY message is not reached? When will slave then pull the update? Lets take an example 12.05 I updated the zone and reload it 12.06 xfer.out shows the update is sent but Internet link at slave is down. Link is back at 12.20. When will then slave receive update? ___ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
