LSP Size Oversubscription
For LSP size oversubscription, you simply configure less bandwidth than the peak rate expected for the LSP. You also might need to adjust the configuration for automatic policers. Automatic policers manage the traffic assigned to an LSP, ensuring that it does not exceed the configured bandwidth values. LSP size oversubscription requires that the LSP can exceed its configured bandwidth allocation.
Policing is still possible. However, the policer must be manually configured to account for the maximum bandwidth planned for the LSP, rather than for the configured value.
