Lab: Using IS-IS Metrics
Despite the standardization of wide IS-IS metrics in 2004, most vendors continue to use outdated narrow metrics by default.
MAIN POINTS
- Wide IS-IS metrics were standardized in RFC 3784 in June 2004.
- Most vendors still default to using narrow IS-IS metrics.
- The blog post critiques vendors' default settings for IS-IS metrics.
- Additional details are available in the "Using IS-IS Metrics" lab exercise.
TAKEAWAYS
- Understanding IS-IS metrics is crucial for network optimization.
- Vendors' default settings may not align with current standards.
- Exploring lab exercises can provide deeper insights into IS-IS metrics.
- Awareness of metric standards can influence network configuration decisions.
