IOS/XR Route Redistribution Configuration Mess

The implementation of route redistribution for OSPFv2/OSPFv3, IS-IS, and BGP on IOS/XR revealed inconsistent syntax for the source routing protocol in the redistribute command across different protocols.

MAIN POINTS
  1. IOS/XR developers did not standardize configuration features for routing protocols.
  2. Route redistribution, termed as route import in netlab, was implemented for various protocols.
  3. Each routing protocol uses different syntax for the source routing protocol in IOS/XR.
  4. The issue was encountered on Cisco 8000v running IOS/XR release 24.4.1.
TAKEAWAYS
  1. Standardization in network operating systems is crucial for consistent configurations.
  2. Developers should avoid reinventing common configuration features unnecessarily.
  3. Understanding different syntax requirements is essential for effective route redistribution.
  4. Testing on specific hardware and software versions can reveal unique configuration challenges.
