[LARTC] Multipath routing problem.

[LARTC] Multipath routing problem.

[Pierrick Hascoet]

Hi,

I'm currently trying to set up two link with multipath routing as follow:

            / ---- Link 0 ----X eth0 
Core <-----X                         Linux box ---->
Router      \ ---- Link 1 ----X eth1

The goal is to provide big bandwidth at nice price.
with a Core router making multipath routing with equal coast.

Each ethernet interface on the linux box is a /30 network which
is working correctly. But when i try to activate multipath routing with
command as follow, always one link is marked as dead.

ip route add default nexthop via <gw0> dev eth0 nexthop via <gw1> dev eth1

default
	nexthop via AAA.AAA.AAA.AAA dev eth0 weight 1 dead
	nexthop via BBB.BBB.BBB.BBB dev eth1 weight 1

In which case does this problem can occurs ?
Don't hesitate for more informations.

Kernel : 2.4.12
iproute2 : ss010824

Regards,

Pierrick.

	Is the eth0 interface down?

No, the eth0 interface is up and working correctly, i can ping the router
which is directly connected to eth0.

Best regards,

[LARTC] Multipath Routing Problem

[-- Attachment #1.1: Type: text/plain, Size: 396 bytes --]

I currently have 4 DSL lines set up to load balance for my lan. The
multipath works fine for connections the originate from the linux gateway
(such as browsing the internet in KDE or using wget), but all the traffic
from hosts on the lan is routed through only one of the DSL lines (as seen
using ntop and 'ip route show cache') . What would cause this to happen?

Thanks

Charlie Meyer
