SR OS Router Procedures on Receiving a PCInitiate Message

  1. If a PCInitiate message includes a name that is a duplicate of an existing LSP on the router, the system generates an error.
  2. The router assigns a PLSP-ID and looks up the specified PCE-initiated LSP template ID, if any, or the default PCE-initiated LSP template, to retrieve the local parameters, and instantiates the SR-TE LSP.
  3. The instantiated LSP is added to the TTM and is used by all applications that look up a tunnel in the TTM.
  4. The router crafts a PCRpt message with the Tunnel-ID, LSP-ID, and the RRO and passes it along with the PLSP-ID set to the assigned value and the delegation bit set in the LSP object to the PCE.
