A month and a half late, but what you can do is:
- Hidden master, owns the zones but is not advertised, except in SOA - Zones are dynamic, you learn to make updates with NSUPDATE, pointed at the master - CRON job in the master to freeze-backup-thaw the zones as often as your backup policy says - Multiple slaves learn the zones from the master via XFR - The slaves listen on a loopback address, which is the same address in every slave - Each slave runs a routing daemon and advertizes the loopback address as a specific /32 or /128 to his upstream router - All clients are configured with the IP Anycast address, and you have NS record for the IP Anycast address - You run a monitoring script in each slave, so that if NAMED stops being available or stops giving sensible/correct answers, then the script: - sends a "KILL -9" to NAMED - withdraws the route from the routing daemon - downs the loopback virtual interface - sends you an email/page/rings an alarm Really, many people have solved this, in much the same way. It is almost a standard pattern. -- david t. klein Cisco Certified Network Associate (CSCO11281885) Linux Professional Institute Certification (LPI000165615) Redhat Certified Engineer (805009745938860) Quis custodiet ipsos custodes? -----Original Message----- From: bind-users-bounces+root=nachtmaus...@lists.isc.org [mailto:bind-users-bounces+root=nachtmaus...@lists.isc.org] On Behalf Of Kaushal Shriyan Sent: Friday, September 14, 2012 6:37 AM To: bind-users@lists.isc.org Subject: DNS BIND Failover Setup (High Availability) Hi, Can someone please point me to setup High Availability BIND DNS Server on CentOS Linux version 5.8?
