In this example the communication between vsys is within the palo alto. But in my example i have L3 device via which vsys1 & vsys2 are communicating, then how should be the policy ?

Thanks.

@nitesharbale,

You just need to create EXTERNAL type of zone which will allow to communicate traffic between the zones which belong to different vsys. Once zone is created, you need to add security polices that allows communication between local zone and external zone. Article shared by @BPry have all these details.
