- Renamed and to and respectively across various test files and modules. - Updated response codes in tests to use new definitions (). - Added new testbench to validate RIB to RAM interactions. - Created for testing RIBP topology routing. - Adjusted memory map tests to reflect new interface names. - Ensured all references to old interface names were replaced in Python test scripts. - Verified that all test cases pass with the new interface structure.
