Hello,
I encountered the same issue after a V2T migration.
To resolve the issue on the MAC, I created a specific MAC Discovery Profile with MAC Learning enabled and attached it on Mobility Master Segment.
Then I followed the recommendation of . I created a new service with a service entry with type = IP and Additional Properties = VRRP
I created a new rule with src/dst = Mobility Master group and the service previously created.
And it works. No more flapping.
Thanks to have create this topic and for your tips.
