Dear people, I have two sites: - Main site with an Internet link and two BIND services (DNS1 y DNS2) and a /28 block, and web and mail services supported - Backup site with a second Internet link and a BIND service (DNS3) and another /28 block
When the Internet link from main site is DOWN, the web and mail traffic come through the backup site to main site crossing a L2L. So I need to change the IP's of the FQDN hosts I have supported in the DNS3 in order to continue offering services (web and mail). How can I do this automatically? Is there any way that "something" monitors the main Internet link and in case it is DOWN automatically order to modify the FQDN records in DNS3 ??? Thanks a lot and regards!!!
