第一个问题 :
notify
If yes (the default), DNS NOTIFY messages are sent when a zone the server is in is authoritative for changes. The messages are sent to the servers listed in the zone's NS records (except the master server identified in the SOA MNAME field) and to any servers listed in the also-notify option.
If explicit, notifies are sent only to servers explicitly listed using also-notify. If no, no notifies are sent.
The notify option may also be specified in the zone statement, in which case it overrides the options notify statement. It is necessary to turn off this option only if it causes slaves to crash.
我想就不需要AB了吧。
第二个问题 一时我也说不清楚,呵呵。或者说我概念也不是很清楚,你再看看文章吧。 |
