CNI Overlay - Reuse Service CIDRs

[swordfish291]

Hello Team

In Azure CNI Overlay mode, we know that pod CIDR ranges can be reused across multiple AKS clusters. I’m wondering if the same approach applies to Service CIDRs.

The documentation clearly states: “The range should not overlap with the pod CIDR range, cluster subnet range, and IP range used in peered VNets and on-premises networks.” However, it doesn’t explicitly mention whether the Service CIDR can or cannot be reused across different AKS clusters within the same VNet or peered VNets.

Is reusing the same Service CIDR across multiple AKS clusters a recommended or supported approach?
