Persistence configuration in the F5 LB (LTM 3400)

We are having a Network set up where we have 6 pool of Servers sitting behind the F5 Load Balancer (F5-LTM 3400).

 

 

In this setup , below is required in the F5 LB configuration to handle the following type of requests hitting the LB from outside and then F5 doing the loadbalancing with persistence among 6 MSDP servers :-

 

 

1) Requests hitting with MSISDN No.

 

 

In this case , Requests should get Load Balanced with persistence among 6 servers based on MSISDN No.

 

 

 

2) Requests hitting with Jsession ID and without MSISDN No.

 

 

In this case , if requests are coming with Jsession ID and without MSISDN No. , then Requests should get Load Balanced with persistence among 6 servers based on Jsession ID

 

 

 

3) Requests coming without both MSISDN No. and Jsession ID.

 

 

If both MSISDN and Jsession ID are not present in the request then there should be a fallback persistence on the basis of which requests should get loadbalanced with persistence based on say Source Address.

 

 

 

Looking for suggestions if anybody has implemented the above or have some idea.

 

 

Regards
