HA Failover without session drops/failures
I know this was asked before, but I think things have changed since it was asked.
I have a web service application.
The configuration looks like: IPv4 Virtual is a passthru to IPv6 (using an iRule to select the IPv6 virtual). IPv6 virtual has Client/Server ssl profiles and HTTP profile. There is also an iRule for pool selection.
I put mirroring on the IPv4 virtual, added it to both the client/server ssl profiles and to the SNAT.
When I fail over, under load, the load generator gets lots of connection timeouts.
Runing 11.6 HF1 on an 8900 FIPs device.
I'm at a bit of a loss as to what else I could be missing. I did get an error when trying to turn on connection mirroring on the SSL virtual:
Connection mirroring is not supported in combination with a Client SSL or Server SSL profile.
I thought that's what the new SSL mirroring feature was s'posed to address though.
