PR Number Synopsis Category: Multiprotocol Label Switching
1145627 During FRR, juniper MP does not send label sub-object in RRO for the backup LSPs...
This issue is related to RSVP-TE FRR (RFC 4090) interoperability between Juniper Networks and Cisco devices. If Juniper Networks is the PLR (point-of-local-repair), then it does not set the "label recording desired" flag in the backup path messages. Also, Juniper as the merge point (MP) does not send the label sub-object in the RESV RRO for the backup LSPs. However, the Cisco PLR sends the backup path message with the "label recording desired" flag set and expects to see the label sub-object in the corresponding RESV RRO. So as a result, in the scenario where the Cisco device is the PLR and the Juniper device is the MP, a change in the RESV label while protection is in use at the PLR will not get propagated upstream beyond the MP.
