Traffic engineering advertisements are triggered when a threshold value is reached or crossed. For all other bandwidth changes, a periodic flooding timer or Connection Admission Check (CAC) failure triggers the TE advertisements. When no thresholds are crossed, changes are flooded periodically unless periodic flooding was disabled. Configurations can be executed as a global configuration or interface specific configuration.
Interface specific configurations supersedes global configuration and default values. Global configuration supersedes default values. When there is no interface specific configuration and global configuration, then the default values are used.
