Ideally it would just omit the metric, but with the current RFC, that isn’t an option. Note that these same metrics are optional in Destination Up and Update. They are optional in Dest Up/Down because you are allowed to report a default value for all neighbors in the Session Initialization and it will just be valid for all neighbors. Henning Rogge
