Hierarchy Level


Configure a time duration for which the BGP allocated MPLS labels are retained after they go stale. Holding the stale labels without deleting them immediately allows the upstream peers to receive and install the new labeled advertisements. Note that these MPLS stale labels are retained even when MPLS fast reroute (FRR) is not configured.


During this hold down period you cannot use the label space for new label allocation, which momentarily reduces the supported label scale. Therefore, we recommend setting an appropriate minimum value as the hold down time period for stale labels.



Specify a time duration in seconds for which the MPLS labels allocated by BGP are kept after they go stale.

  • Range: 1 through 600
