I created a unicast setup. It was an experiment to verify if I could make my PTP-service more resilient against 'rogue' masters on the same VLAN that (falsy) claim to be the best master.A back actor on the LAN can easily spoof your unicast GM soruce address, so using unicast is does not mitigate that security risk.
True. This was more about 'accidental' failure, rather than malicious intend.
It would be more development work to actively avoid multicast. It would not be impossible, but for me there would need to be a strong motivation to justify the effort.
I see.Perhaps that time is better spend on implementing PTP V2.1 (IEEE 1588–2019) Annex P in due time? ;-)
Thanks. -- Marco
