- Updated test cases in , , , , , , , and  to replace references from RIB to RIBP.
- Modified file names and paths in tests to align with the new RIBP naming conventions.
- Ensured that all assertions and checks in the tests are consistent with the updated RIBP interfaces and functionality.
- Added a new test for migrating user core RIBP interfaces in .
