Load balancing using Cisco Asa Firewall

[sv7]

Hello All,

Please check attached Diagram.

Have two ISP Connection connected to Cisco Asa Firewall. Basically i want my subnet 172.16.1.0/24, 172.18.2.0/24 traffic should go via ISP1 and only subnet 172.21.20.0/24 traffic should go via ISP2. 

Is it achievable in Cisco ASA ?. IF yes please guide me how can i achieve it or share any related configuration document.

Thanks in advance

You want to use Policy Based Routing (PBR), examples:-
