The single most important piece of advice I can offer when building your own tools: Never poll the routing table with SNMP. Ever. Any OTS tool that says it can, as a feature, well, it's a witch, burn it. (
You mean like the Cisco Route Manager? *http://www.cisco.com/en/US/products/ps6336/index.html * I not used it myself but the datasheet does say it collects the routing tables via SNMP, with the one cavet: "Prior to a scan, the Cisco Route Manager checks the router's CPU and if the percentage is greater than a configured threshold then it does not scan the route table and moves onto the next router."
