Can I use "Source based routing" in ACI multisite?

[SIMMN]

Here is the use case:

I have two ACI sites (A and B) and running as multisite architecture. Each site has its own local only networks and there are also networks are L2 stretched between the sites. Each site has its own local L3Out (EIGRP based as an example). For a workload on the stretched network running in site B, I want its outbound traffic, such as Internet traffic, to exit the ACI fabric using site A's L3out (intersite L3Out). But I want the workloads on site B local only networks to still use site B's L3out for outbound traffic.

With the traditional network devices (IOS or NXOS), I can do policy-based-routing route-map to match source and set next-hop to route traffic differently. But not sure if I could do the similiar in ACI...Please advise.

 Hey @SIMMN In Cisco Application Centric Infrastructure (ACI) Multi-Site deployments, source-based routing is not natively supported in the same way it might be in traditional networking environments. ACI Multi-Site is designed to provide a consistent policy and network model across multiple ACI fabrics, but it primarily relies on policy-based routing and other ACI-specific mechanisms to manage traffic flows.

Let me know if you need details to achieve similar outcomes to source-based routing within an ACI Multi-Site environment by leveraging ACI's policy-driven approach and advanced features.
