    Hi Saravanan,

     

    On your core switch, there should be no SVI/VRF for the vlan of the Server Farm. This will break your configuration. Your setup will only work if your server vlan is a L2 vlan on the core switch.

     

    Cheers,

Your welcome Saravanan,

 

Both your vlan's are connected to the core and the BIG-IP on L2, but the real server vlan can only be found by the core via the BIG-IP. If this vlan is a L3 vlan the Core will sent traffic to the real servers directly instead of via the BIG-IP. This created asymmetric routing.

 

Your network setup is like the picture:

 

Cheers,
