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. See: Farrel, A., Interim Report on MPLS Pre-emption, draft-farrel-mpls-preemption-interim-00.txt, work in progress
