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.

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.

When configuring an L3Out in Cisco ACI and encountering a QoS-related error, creating a custom QoS policy is often necessary to clear the fault. This involves defining a QoS policy that meets the specific requirements of the L3Out configuration and applying it to the relevant interfaces or globally within the fabric. The custom QoS policy should be designed to prioritize traffic appropriately and ensure that the necessary QoS settings are in place for the L3Out connections1.
