As soon as the leaf switch detects the MAC has moved, L2 Forwarding Manager (L2FM) will send a notification to
HMM in order to update the local HMM entry for IPv4 and IPv6 as necessary. Below you can verify that the local HMM
entry still temporarily exists, but points to the remote FP switch-id of the leaf the host moved to

Finally, a notification from ARP Adjacency Manager triggers HMM to flush the local entry for 20.10.100.11. This com-
pletes the move operation. Typically, these two operations happen within the same second for a production DFA envi-
ronment. Below you can see the arp table with the respective host, as well as the events that verify the table being
populated.
