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."
