You mean like the Cisco Route Manager?
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."
