 Description   

Hi,

I have a very simple topology with a Cisco IOS XRv (7.0.2) and ODL v14.1, running PCEP between both.

Then I'm creating a new SR LSP with ODL, which results in the creation of the LSP in the router however the PCEP topology in ODL is not updated and no LSP appears in there.

A work around is to shutdown and start ODL again, then the PCEP topology is properly populated.

I can provide a wireshark trace of the flow and the e debug output from PCEP in ODL.

Step to reproduce:

  1. add a new LSP (topo not updated)
  2. reboot ODL (topo up to date)

Can you post the karaf.log files for both before and after the reboot, please?
I strongly suspect this is related to BGPCEP-881, but we need to understand more about what is going on.

I have attached the logs from ODL version 0.13.1 and a capture of the exchange between the router IOS XRV (10.0.0.3) and ODL (192.168.1.10) in case that would help.

Steps to reproduce:

1. Create a LSP (name PCEP16112021-1) => LSP appears in the topology
2. Create another LSP (name PCEP16112021-2) => LSP doesn't appear in the topology
3. Restart ODL => both LSP's are in the PCEP topology
