<p class=MsoNormal>Anyone out there using GSLB with A-RTT as the secondary
metric (first being health check of course) and the tie breaker being round
robin.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>I have a GSLB enabled under those settings and when the TTL
times out for the initial answer the other site is issued as the answer for the
next time around, aka “flip flopping”.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>Both sites are in N-AM.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>I would expect the flip flopping if the A-RTT data were
equal but it is not.<o:p></o:p></p>
<p class=MsoNormal> <o:p></o:p></p>
<p class=MsoNormal>Any additional details info needed to understand the
situation please ask.<o:p></o:p></p>
