To address resource overconsumption on a border leaf switch, migrating L3Outs to another switch can help distribute the load and reduce strain on the affected switch.

Before associating a schema with a newly configured site in Cisco ACI Multi-Site Orchestrator, it’s essential to configure a provider. This establishes a communication link between the orchestrator and the sites, enabling proper deployment and management of objects across multiple sites.

The minimum MTU value that must be supported by the ISN to allow control plane endpoint information exchange between sites in a Cisco ACI Multi-Site setup with default settings is 1554 bytes (B). This accounts for the standard MTU of 1500 bytes plus additional overhead for VXLAN encapsulation. An MTU of 9000 (A) or 9100 © is not the minimum required, and 1600 (D) is not related to the default fabric settings5. References := (Multi-site / Multi-Pod MTU Jumbo Frames5)
