- Cisco's documentation defines "passive" as suppressing OSPF protocol operations on an interface.
- The OSPFv2 passive interface test fails with a "neighbor is in Init state" error.
- This error is unique to Cisco IOS/XR among over two dozen tested platforms.
TAKEAWAYS
- Even well-documented configurations can lead to unexpected results on different platforms.
- Testing across multiple platforms can reveal unique and unforeseen issues.
- Cisco IOS/XR's handling of "passive" differs from other platforms.
- Continuous testing is crucial for uncovering platform-specific quirks and errors.
