Dagv2 tables are randomized and may change when a tmm is restarted. This can result in a change of traffic distribution, which in some cases may lead to traffic disruption. The specific condition when this option was introduced is using a CGNAT pool that is not large enough. Other ways of encountering include increased translation failed errors following an upgrade or restart or blade replacement.
- dag distribution changes which may cause a traffic disruption.
- tmm is restarted (or chassis rebooted)
You can restart tmm until the distribution is good, which can be checked using tools like cmp_dest.
