Is there a way to disable the routing cache? Using the command ip route flush cache only temporarily erases entries in the kernel's cache file. The same goes with writing to the file /proc/sys/net/ipv4/route/flush. I have not been able to find anywhere on the Internet a way to actually disable it so that the kernel doesn't even maintain a cache. I believe this requires a modification of the kernel. Does anybody have a solution or any info to this problem? Help would be greatly appreciated.

If I find a way to disable the routing cache, I would also like to do disable the multicast routing cache. Using the following command displays the multicast routing cache:
ip route mroute show

I'm bumping this thread as I have the same requirements for Redhat 9.

The reasoning for wanting to disable the route cache is to effectively use load balacing with two net connections. By using multi-threaded clients for HTTP/FTP you can achieve a higher combined transfer rate by routing multiple requests to the same download out each connection.

The problems is obviously that with a route cache, it routes each subsequent connection to a host out the same interface, which basically defeats the purpose of the load balancing.

I have used the same techniques as RSalameh to flush the cache, but I've found it causes issues with existing connections (connection resets etc).

I am not a linux expert and get the feeling im trying to run before I walk.

Any input would be greatly appreciated.
