Disabling route cache

Disabling route cache

[ken]

I am building Linux routers with multiple DSL WAN links. I'm using
iproute2 to load balance users onto the Internet. However, with IP route
cache the result is sometimes poor. Is there a way to disable route
caching in the kernel.

						Thanks, Ken

If the problem is that after a link/ISP failure some already stablished
connections or new connections use the cached route to go through the
failed link, you can make the kernel forget about any route caches it
currently has with the command:
# ip route flush cache

You can check the routing cache at any time with:
# ip route show cache

Hope it helps.
