Hi,
I know certain load balancers which have priority based pool member activation for e.g. the server farm has two rservers. And all the traffic is sent to Rserver1, even though Rserver2 is live.
The traffic is forwarded to Rserver2 only when Rserver1 is down.
Is this possible with Cisco ACE ?
Thanks.

Hi,
Yes this is possible. Use the backup-rserver option.
E.g.
serverfarm host SF-App
rserver server1
backup-rserver server2
inservice
rserver server2
inservice standby

Thanks.
What if I need to cover both ways i.e.
If R1 fails R2 takes over. And when R1 comes up or when R2 goes down, R1 takes over (if available) from R2.

The config does what you want. In all cases on the ACE, the backup - be it server or serverfarm relinquishes control when the primary comes back.
Kind Regards

Hi,
in the example above, when R1 fails, R2 takes over. From the moment R1 becomes alive again, R2 goes again into standby state, so all traffic is send again to R1.
If R2 fails, nothing will happen because it was in standby state.
HTH,

Cathy,
You rule; I just got a request to do what you just described.
Thank you,
