Hi, My colleagues and I have a couple of questions regarding the first para of Section 15.2 of 8432bis<https://datatracker.ietf.org/doc/html/draft-ietf-bess-rfc7432bis-14#section-15.2> "Sticky MAC Addresses".
This para says: <quote> There are scenarios in which it is desired to configure some MAC addresses as static so that they are not subjected to MAC moves. In such scenarios, these MAC addresses are advertised with a MAC Mobility extended community where the static flag is set to one and the sequence number is set to zero. If a PE receives such advertisements, then it MAY program to drop any received frames with that MAC SA over its local ACs. When a PE later learns the same MAC address(es) via local learning for remote PEs or via a different ES for the advertising PE, then the PE MUST alert the operator and MAY drop the received frames. <end quote> 1. What should happen if a certain PE first locally learns a specific MAC address from the DP and later receives an EVPN Type 2 route advertising the same MAC address with the MAC Mobility Extended Community reporting it as "sticky"? Should the operator be alerted about this event? 2. Can you please clarify what exactly you mean by the marked? Your timely feedback would be highly appreciated.
