The following CLI displays are output examples of a PCEP SR-TE LSP in three configurations:
-
PCE-computation enabled, PCE-report disabled (via inheritance), and PCE-control disabled
-
PCE-computation enabled, PCE-report enabled, and PCE-control disabled
-
PCE-computation enabled, PCE-report enabled, and PCE-control enabled
The configuration can be determined by checking the PCE Report, PCE Compute, and PCE Control fields. An example of the output is shown below. For more information and CLI output examples, see the show>router>mpls>sr-te-lsp command description.
