In a two-pod Cisco ACI Multi-Pod environment, it is recommended to deploy no more than two Cisco APIC controllers in the same pod to avoid losing all replicas of a shard if a pod fails. The APIC cluster is a distributed system where each APIC contains a replica of the configuration database, referred to as a shard. If all replicas of a shard were located in the same pod and that pod were to fail, it would result in the loss of the shard and potentially impact the entire fabric’s operation. By distributing the APIC controllers across pods, the risk of losing all replicas due to a single point of failure is mitigated, enhancing the overall resiliency of the system1.

ACI Multi-Pod White Paper - Cisco1

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 set Layer 2 loop migration in an ACI Fabric with a Layer 2 Out configured, MCP (Misconfiguration Protocol) must be enabled on the ACI fabric56. MCP helps to prevent Layer 2 loops by detecting misconfigurations that could potentially cause loops56.
