Questions about DNS timeouts
If a DNS request to the dns-ip-primary does not receive a response within the allotted time (dns-timeout), SBC queries the dns-ip-backup1.
From then on, it seems that all subsequent requests are redirected to the dns-ip-backup1. Under what conditions does the SBC switch its DNS queries back to the dns-ip-primary?
Is there an automatic mechanism for the SBC to revert to dns-ip-primary?
Thanks a lot,
Olivier
