EPNM 8.1 version EPL service LSP OAM failure symptom

[backdhh]

Hi Team.
Currently, in EPNM8.1.1 version, after configuring the EPL service for NCS5504 and ASR903 equipment, a failure occurs when looking up LSP OAM. I am wondering if this is a problem with the software XR and XE versions or if it is supported.
NCS5504 Sofware version  25.1.2 / ASR903  Sofware version 17.9.7 
- Log history 

- ASR903 <-> ASR903 

Normal confirmation via NCS5604 when configuring between equipment

Thank you

This is likely due to an interoperability issue between NCS5604 and ASR903. EPL provisioning is supported on both platforms, but MPLS OAM between XE and XR nodes may be causing your issue. You also need to make sure that OAM is configured correctly on both devices and that the IGP is properly configured. Check the EPNM logs to see what is happening.

After that, I would recommend getting in touch with Cisco TAC to see if there are any known compatibility issues between the two hardware platforms.
