Release introduced: 25.8

In NSP 25.8, the delay path metric is added to PCEP messages. This communicates the latency thresholds of a path. Updates to the delay metric are sent down to PCCs via PCUpdate PCEP messages when a path changes or when the LSP is re-signaled after the metric has changed.

Release introduced: 25.4

An end-to-end LSP can be configured with 'Include Route Object' defined, thereby creating a Nominal Path that will prevent the LSP from rerouting. This feature introduces an additional setting that will ensure the BSID does not reroute either. This enables consistent end-to-end behavior from the LSP.
