In the above scenario, every traffic is going via L3out-1 where the default route is given and using next hop 20.1 but the condition is if SIP- 10.10.10.10 and DIP is 14.14.14.14 then the next hop should be 30.1 and traffic pass via L3out-2 instead ...

Can we make ACI fabric up with a single spine switch and after 10-15 days I want to add the second spine in the fabric. Is it possible...? If possible, please let me know the procedure...... 

Can anyone help me with the PBR configurations in ACI without using L4-L7
