We have two CSS devices set up as DNS host for our failover scenario.
This works well, but I had a question about the TTL in the config for the DNS a-record.
Currently our records are set as follows:
dns-record a http://www.mycompany.com 188.8.131.52 50 single kal-icmp 172.16.2.2 254 sticky-disabled weightedrr 0
My questions are:
What is the TTL setting as far as the client doing?
Does the client, when getting the name resolved via the CSS, know that the ttl is 50 seconds and will not try again to hit the CSS until after the 50 seconds is up?
