 Description   

ODL returns PCerror message for any PCreport message sent by PCC

 Version : Aluminium ----opendaylight-0.13.1

Steps:

  1. Create a pcep session between pcc and pce(ODL)  with segment routing capability
  2. Initiate an SR lsp from pce(ODL)
  3. PCC should be sending a PCreport message for the pce init message from ODL
  4. PCerror message indicates that "LSP object is absent in pce report" but pcc is sending LSP object in it pce report message

Observation:

pce(ODL) returns PCerror message on reception of PCreport message from pcc.

 Version : Aluminium ----opendaylight-0.13.1

Do you have karaf.log available from the run? It should contain a wee bit more information.

Comment by Olivier Dugeon [ 22/Jul/21 ]

This is due to the order PCEP Objects are serialize by the PCC. In old draft, LSPA Object follow ERO while in RFC it follows RRO.

We are working on this issue. A first solution has been proposed, but we are looking to a more generic approach to solve this issue and others that are similar. Indeed, we must be sufficiently flexible to handle PCC that follow RFC and those that follow old draft.
