IETF 100, November 2017 Singapore MAC move/flush over Geneve encapsulation draft-boutros-nvo3-mac-move-over-geneve-00 Sami Boutros Jerome Catrouillet Ankur Sharma Vmware IETF 100, November 2017 Singapore

MAC Move/Flush signaling – use case NVE-6 L2 Access Network NVE-5 NVE-1 NVO3 Geneve Fabric Layer2 DHD NVE-4 NVE-2 NVE-3 Primary Standby MAC Move/Flush signal

Why do we need MAC Move/Flush? An inband data plane OAM mechanism for MAC flushing over GENEVE tunnel. Faster convergence on failover to move or flush MAC learned in data plane from active to standby node.

MAC Move/Flush signal New GENEVE option TLV. Sent on failover by backup NVE over the GENEVE Tunnel for the L2 logical segment identified by the VNI number to move or flush the MACs learned via the old active NVE. Receiving NVE sets the ACK bit in the response In absence of ACK, sender retries 3 times at one second interval. An ACK receipt with higher sequence is implicit ACK for all lower sequence sent.
