Refer to the exhibit.

To enable inter-VRF communication, the following configurations are necessary:

Set the subnet scope to Shared Between VRFs: This allows the subnets to be shared across different VRFs within the same tenant or across tenants, enabling communication between EPGs that are in different VRFs1.

Export the contract and import as a contract interface: By exporting a contract from the provider tenant and importing it as a contract interface in the consumer tenant, you establish a relationship that allows for controlled communication between EPGs in separate VRFs or tenants1.
