Usage Guidelines MPLSLM instances periodically trigger path discovery requests for LSP groups. At certain intervals, an

MPLSLM instance begins triggering path discovery requests for each group in ascending order (determined by group ID). By default, the path discovery requests are triggered sequentially, although some concurrency may occur if the session limit value is greater than 1. The cycle concludes when the last LSP group finishes path discovery.

If the duration of the discovery cycle is larger than the scan period, a new cycle starts as soon as the previous one completes.
