Implementing Cisco IP Routing (CCNP ROUTE, legacy) — Question 354

Which three methods can a network engineer use to fix a metric-based routing loop in the network? (Choose three.)

Answer options

• A. Implement offset lists at network boundaries
• B. Filter routes manually using prefix lists
• C. Filter routes based on tags
• D. Filter routes manually using distribute lists
• E. Utilize route database filters
• F. Implement proper network summarization on key routing points

Correct answer: A, C, F

Explanation

The correct answers are A, C, and F because these methods effectively adjust the routing behavior to prevent loops. Offset lists at boundaries help modify metrics, filtering by tags can selectively control route propagation, and proper summarization reduces routing table size, minimizing the chances of loops. Options B, D, and E, while useful for route management, do not directly address metric-based loops.
