# ip ro add dev eth0 default nexthop via 10.0.0.1 dev eth0 nexthop via
10.0.0.202 dev eth0
# ip ro ls
10.0.0.0/8 dev eth0 proto kernel scope link src 10.0.0.11
default
nexthop via 10.0.0.1 dev eth0 weight 1 dead
nexthop via 10.0.0.202 dev eth0 weight 1

10.0.0.1 however is far from dead, if we add yet another nexthop:

# ip ro add dev eth0 default nexthop via 10.10.10.10 dev eth0 nexthop via
10.0.0.1 dev eth0 nexthop via 10.0.0.202 dev eth0

# ip ro ls
10.0.0.0/8 dev eth0 proto kernel scope link src 10.0.0.11
default
nexthop via 10.10.10.10 dev eth0 weight 1 dead
nexthop via 10.0.0.1 dev eth0 weight 1
nexthop via 10.0.0.202 dev eth0 weight 1

This first nexthop is *always* declared dead. Linux 2.4.x, iproute 20010824.

If anybody can point me in the direction of this problem, it must be known
as it has been there for a *long* time, it would be appreciated. I'll try to
fix it.

Thanks!

Regards,

bert
