SIP Message Based Load Balancing

Hi

 

I am finding it difficult to make SIP MBLB work on BIG-IP 11.2.0 Virtual Edition.

 

Client side is SIP TCP with large number of connections...Server side want to have a pool (instead of 1:1)

 

Followed the instructions in http://support.f5.com/kb/en-us/solutions/public/13000/500/sol13575

 

Got 2 pool members & min-conn set to 4. However F5 is making 1-1 connection instead of creating/re-using pool of connections.(in this case it should ideally be 2/pool member)

 

 

 

 

 

Is this a standard configuration supported for SIP profile or is an iRule required to achieve this

  • Do you mind sharing the mblb profile that you are using? As long as it is applied to the VIP it should work based off those instructions.
  • Pls find the mblb profile & VIP details

     

     

    ======

     

    ltm profile mblb /Common/snpmblb {

     

    defaults-from /Common/mblb

    ingress-low 9000

    min-conn 4

     

    tag-ttl 60

     

    }

     

     

     

     

     

     

    ltm virtual /Common/snpsip {

     

    destination /Common/192.168.3.203:1979

     

    ip-protocol tcp

     

    mask 255.255.255.255

  • Hi

    Has anyone else faced similar issue?

     

    What irule is required to make this work...just the configuration doesn't seem to suffice
