Interoperability tests between various vendors for this specification has been tested by EANTC for several years now. Specifically, please refer to this test report from the 2019 event:
https://eantc.de/fileadmin/eantc/downloads/News/2019/EANTC-MPLSSDNNFV2019-WhitePaper-v1.2.pdf
BGP SR Policy SAFI usage for signaling between controller & routers; also steering based on Color Extended Community - refer pages 26-27
Also covered in later years:
https://eantc.de/fileadmin/eantc/downloads/events/MPLS2020/EANTC-MPLSSDNNFV2020-WhitePaper.pdf
https://eantc.de/fileadmin/eantc/downloads/events/2022/EANTC-InteropTest2022-TestReport.pdf
Interoperability testing does not cover error conditions and handling of malformed/invalid updates.
