If user hosts migrate between different gateways in a distributed VXLAN gateway scenario and do not send gratuitous ARP or NA packets after the migration, you can configure user host information update triggered by a MAC address entry change to ensure that user hosts can successfully go online after the migration. After this function is configured, the switch can be triggered to send ARP or NS requests to update user host information by changes in the user hosts' MAC address entries on the switch before and after the migration.
