[BGPCEP-1008] ODL Sulfur : PCEP Session terminates when a PCReq is received . Log shows "Compute path from Source Null"

Wed, 8 Jun 2022 12:06:08 +0000

Description

Initially , the BGPLS topology ( bgp-example rib ) and the Graph topology ( mapped using example-link-state-topology) is correctly populated ( GET response of linkstate routes and Graph topology attached) . The PCEP session between this PCE and our PCC is also successfully established ( GET response of pcep-topology attached ).

When i send a first PCRequest ( either for RSVP TE tunnel or Segment Routing MPLS tunnel) , the PCEP session is terminated by the PCE .

In the log file, i see the message "Compute path from Source Null" after which an exception is raised.

After this, the PCEP sessions keeps flapping.
