LARTC - Sep 2005 - ip route add default mpath (rr| drr|random|wrandom)...

Anyone using it? I''ve tried but after about 5 min I always get kernel
panic. My setup is based on nano.txt. I works well but only if
CONFIG_IP_ROUTE_MULTIPATH_CACHED=n. I just wanted to play with the new mpath
feature of ip. But enabling CONFIG_IP_ROUTE_MULTIPATH_CACHED always resuts in
kernel panic. I''m not using any kernel patches from
http://www.ssi.bg/~ja/ - are they needed at all? - They do not apply cean. The
kernel is 2.6.13.
This configuration does not work:
CONFIG_IP_ROUTE_MULTIPATH=y
CONFIG_IP_ROUTE_MULTIPATH_CACHED=y
CONFIG_IP_ROUTE_MULTIPATH_RR=m
CONFIG_IP_ROUTE_MULTIPATH_RANDOM=m
CONFIG_IP_ROUTE_MULTIPATH_WRANDOM=m
CONFIG_IP_ROUTE_MULTIPATH_DRR=m

How should i use these modules? ip route add default mpath (rr|
drr|random|wrandom)... does not load the appropriate module automatically.
Loading them manualy changes nothing. And issuing this command on kernel where
this feature is not enebled  does not report any error.

	2.6.14-rc2 comes with fixes for CONFIG_IP_ROUTE_MULTIPATH_CACHED,
but i declare that my routing patches are not compatible with this
feature, until someone proves that both features work together.

Ok. I just wanted to know what are your patches supposed to do. I as far as i
know they help when i have multiply links attached to one interface - for
example 3 dsl modems attached to one switch and this switch to 1 ethernet port
in the serwer.
Can these patches do something more?
So ip ... mpath ... is broken at present?

In the previous mail i wrote that i''m not using patches from
http://www.ssi.bg/~ja/ but actually i
am. I was doing various experiments and finally 
ended with the patched kernel. But forgotten it ;) And this configuartion worked
fine: kernel with patches from
http://www.ssi.bg/~ja/ and with CONFIG_IP_ROUTE_MULTIPATH_CACHED=n.
Kernel without these patches also works but not so good. Do not work or work
bad:
ftp, https, online communicators.
I''ve not tested it too much but if it is true than i know now what
these patches do. The route is not changed too fast so given connection to the
remote serwer is always with the same route (isp, dsl, interface - so with the
same source address). This is especially needed if login is required.
