Seemless failover - tcp session

Hi

Wanted to do ltm + apm seemless failover

Thought I could do it with conection mirroring turned on but

https://my.f5.com/manage/s/article/K09115252

seems to suggest you can't have APM fail over and connection fail over .

so my long lived tcp session have to die....

Any one know of a way to do this with out killing the tcp session !!!!

  • AlexS_yb Connection mirroring typically handles this but some connections just wont failover without some sort of disruption. Why the necessity to have absolutely zero downtime for TCP connections?

      Its a requirement from the devs / business. We need to provide a seemless failover

      The PA's do it and the F5's LTM seem to do it, its just when you APM that it will not do it.

       

  • Seems like the current suggest from the current support engineer is

     

    I need to setup

    VS with LTM + connection mirroring

    VS with APM with APM HA

     

    Wondering what type server should I setup the LTM vs and it really seems like overkill
