Enabling the “disable Remote EP learn” feature in Cisco ACI has the effect of preventing border leaf switches from receiving routes through peering with external routers. This feature is particularly useful when there is a mix of Gen1 and Gen2 hardware in the fabric, as it clears all the remote endpoints from the border leaf only. Traffic will still use hardware proxy if the endpoint is not learned on the border leaf, ensuring no operational impact12.

To prevent frequent MAC and IP address moves between different leaf switch ports, enabling rogue endpoint control is the recommended action. This feature helps in identifying and mitigating the movement of endpoints that could potentially cause loops or other issues within the network.
