Chapter 9: UCC-33: LSP Enhanced Path Control

This chapter describes the process required to configure LSP Enhanced Path Control on SR OS NEs using NSP. Two options for telemetry-based optimization, also called enhanced optimization, are presented.

Configuration examples in this chapter show NSP Release 24.4, SR OS 23.7.R2 NEs, and a VSR-NRC  24.3.R3 NE.

The following artifact bundles were used to test this use case:

• nsp-icm-intents-23.11.0-cam-bundle.zip

• nsp-telemetry-cr-va-sros-2.0.0-rel.8 

See the NSP and NE documentation for more information.
