Floating IPv6 addresses are configured with "preferred_lft 0," which
designates them as deprecated. As a result, when the host initiates
traffic, the static network address is selected as the source.
This can lead to situations where the upstream switch does not
observe packets originating from the floating address. Consequently,
the switch may lack the necessary MAC address mapping to deliver
traffic destined for the floating address. While switches are expected
to perform NDP Neighbor Solicitations to discover the floating
address's MAC, this process is not always reliable, especially when
relying solely on external traffic directed towards the host.
To accelerate the network's learning of the floating address's MAC,
the Unsolicited Advertisement (analogous to gratuitous ARP in IPv4) is
transmitted.
This behavior is primarily observed during the initial unlock of
controller-0, before the Service-Manager (SM) takes over the
management of the floating addresses. Subsequent unlocks do not
exhibit this issue.
Test Plan
=========
[PASS] install controller-0 on a AIO-DX configuration (IPv6), execute
network configuration and perform the fist unlock, upon system
return observe from external devices connected to controller-0
interfaces that "Unsolicited Advertisement" are sent related
to the floating addresses.

The starlingx/stx-puppet repository handles the Puppet service1.
The Puppet service runs during bootstrap, and at every reboot, to provide a consistent configuration across the StarlingX system nodes.
This repository is not intended to be developed standalone, but rather as part of the StarlingX Source System, which is defined by the StarlingX manifest2.
