named will do a axfr initially, anytime it believes it has lost sync with the master (the ixfr did not apply without error), when "rndc retransfer" is called, when ixfr is rejected by the master. The master will return a AXFR style IXFR whenever it doesn't have the requested axfr stream. > _______________________________________________ > bind-users mailing list > bind-users@lists.isc.org > https://lists.isc.org/mailman/listinfo/bind-users -- Mark Andrews, ISC 1 Seymour St., Dundas Valley, NSW 2117, Australia PHONE: +61 2 9871 4742 INTERNET: ma...@isc.org _______________________________________________ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
