SW-WAN as edge router in an Enterprise Network (SymmetricTraffc)

Hi,

 

We have 2 Edge Routers and 3 ISP connections, which are connected to both of these routers, as the image bellow.

Now we want to have symmetric traffic. 

Our Provider Independent IP Address is X.X.X.X/22, which we have split it to 4 X /24 addresses.

 

For controlling the incoming traffic, its easy.

Just advertising a specific/24  + the complete /22 address, to each provider. So we are managing, how to receive the Incoming traffic of each of our /24 subnet.

 

How about the outgoing traffic?

As we want it symmetric, so we want to send each of our /24 traffic from the ISP that we have managed to receive the traffic from it. 

 

This can be done via PBR. which makes it complicated in failure scenarios.

 

Can this be done via the 2 Edge routers being SD-WAN routers?
