Object

column Enumeration

This object indicates LSP Preemption type of this LSP:
- unknown: the type is not known
- hardPreemption: the preempted LSP resources are
  freed immediately; the LSP is broken immediately 
  and the traffic is disrupted.
- softPreemption: the resources release pending on the
  reoptimization of this LSP. The head of the LSP 
  reroutes the traffic before the LSP is broken.
- frrSoftPreemption: similar to softPreemption. In this 
  case the traffic of the soft preempted LSP is switched to 
  the backup.
