To configure communication between the EPGs in different tenants, the subnet scope should be set to “Shared between VRFs”. This allows the subnet to be shared across different VRFs, enabling communication between EPGs that are in different tenants but within the same VRF. By marking the subnet as shared, it becomes visible to other VRFs, which is necessary for inter-tenant communication1.

To clear the critical fault related to B2B credit oversubscription in the ACI domain connectivity to the fiber channel storage, the value that should be chosen is 5101. This value is set to address the issue of B2B credit oversubscription and clear the critical fault as reported by the client1.

ACI Multi-Site architecture is designed to interconnect geographically dispersed data centers and extend Layer 2 and Layer 3 connectivity between those locations with consistent policy enforcement. It allows for either a single APIC cluster to manage multiple ACI sites or supports a dedicated APIC cluster per site. This architecture ensures a scalable and flexible approach to managing multiple data center sites, providing a unified policy framework and operational model across the sites34.
