Routing table problems
Routing table problems include but are not limited to:
• inactive routes
• unnecessary routes
• black hole routes
• flapping links (links that go up and come down) that cause the routes to flap
• incorrect route tables
• invalid Address Resolution Protocol (ARP) cache that causes incorrect IP to MAC assignment
• problems with administrative distance or other parameters
Do not restart a device to clear a problem. In restarting the device, you also clear the logs. Logs are
vital and can help determine many problems.
