Disable ip route caching

[vdagost]

Hello,

I use Linux Debian as a router for a school project with Quagga/Zebra. I need to make loadbalancing between routes of the same costs.

It seems to work but the Linux route caching mecanism avoid load balancing to work properly. I can flush manualy the route cache with a while 1 bash script calling ip route flush cache but I'm looking for the good way to do that.

Is there any option, in the kernel configuration I hope, ?
If not what .c file is concerned, maybe I could try to disable route caching by deleting some code ?

Thanks in advance for your help,

deleting code is probably not the best route (hehe get it?).

check under:
/proc/sys/net/ipv4/route/

maybe min_delay...

Thanks for your answer.
Theses parameters improves route caching timers but it's not perfect. I need to completly disable route caching.

How about this then:
Linux Advanced Routing & Traffic Control HOWTO

see section 4.2.2, has link to a patch for loadbalancing.

Thanks a lot, I will try this solution
