Cannot create or update HubVirtualNetworkConnection VWAN

Hi

I have two sites , Aus - 10.0.1.0/24 , US - 10.0.2.0/24

trying to create the Vwan Virtual network connection , but I'm getting error as

Cannot create or update HubVirtualNetworkConnection , cannot be connected because address space overlaps with address space of virtual hubs or virtual networks already peered. Overlapping address prefixes: 10.0.2.0/24..

let me know what might be issue here.

@ValakatlaAshok-0768 , This limitation is expected when you try to peer/add same address space range or overlapping address space VNETs in Azure hub. Please try to use different address space and retry.
