>   My <GateWay IPv6 Addr> is 2001:250:5400:: with prefix length of 64.
>   Each of them works fine on the origin Red Hat 2.4.20-8 kernel, but neither of them works on the USAGI kernel, in spite of much similarity between there configuration. I upgraded it to usagi-linux24-s20030609, but it still refused to work.
>   So I decided to run "ip" command manually to add the route. Then command "ip -6 route add 2000::/3 via 2001:250:5400:: dev eth0" told me "RTNETLINK answers: Invalid argument". But when I change the gateway ipv6 address to 2001:250:5400::1, the route was added successfully. So I tried to change the 2001:250:5400:: format to 2001:250:5400:0:0:0:0:0 and 2001:250:5400:0::, it still didn't work. The ip command is from the usagi-linux24-stable-20030214 kit.

Is it valid to use a scope global address for a route ? By definition
the Gateway is link-local, isn't it ?
I try to do like you by when I make a "ip -6 route add MY_PREFIX::/64 
dev eth0" it tell me that it expect an inet address

But on my lan, using a debian with 2.4.21 usagi 20030713, I don't care
about the default route, my radvd announce my prefix and my box is
configured automagically ;-)

Someone to confirm ?
