LARTC - Oct 2001 - Multipath routing problem.

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.
