debian-ipv6ers,

I'm trying to set up an IPv6 default route without using stateless
address autoconfiguration. In the example below, I want to set up a
default route through a router interface at IPv6 address
fd35:5ab8:3be8:eeee::1, which is on interface eth1:

sudo /sbin/ip -6 route add ::/0 via fd35:5ab8:3be8:eeee::1 dev eth1
RTNETLINK answers: Invalid argument

Setting a route to a specific block also fails:

/sbin/ip -6 route add fd35:5ab8:3be8:1::/64 via fd35:5ab8:3be8:eeee::1
dev eth1
RTNETLINK answers: Invalid argument

I can't tell what is wrong; this appears to be correct syntax. Is there
in fact a syntax error or is something else misconfigured? I am using
the default 2.6.22-3-686 debian kernel.

Thanks,

Bill Cerveny

Do you mean you want all traffic to go out of eth1, or that you want
all traffic to go via a router somewhere else whose address is
fd35:5ab8:3be8:eeee::1 which is reachable via eth1?

You can't specify eth1's address as part of the route.

In this case my system is faulty, because: 'ip route add default via
2001:xMadMad::1 dev sixxs' works well:

$ ip -6 rou sh default
default via 2001:xMadMad::1 dev sixxs metric 1024 mtu 1480 advmss 1220
hoplimit 64


Regards
Friedemann

Could you provide the output of "/sbin/ip -6 addr show dev eth1" and
"/sbin/ip -6 route show dev eth1" ?

Peter,

I want all traffic to go via a router somewhere else whose address is
fd35:5ab8:3be8:eeee::1 which is reachable via eth1.

If I delete the "dev eth1", I get:

/sbin/ip -6 route add ::/0 via fd35:5ab8:3be8:eeee::1
RTNETLINK answers: Invalid argument

/sbin/ip -6 route add fd35:5ab8:3be8:1::/64 via fd35:5ab8:3be8:eeee::1
RTNETLINK answers: Invalid argument

Bill

I don't see what's wrong. I tested the same addresses and routes on my
sarge (haven't moved to etch yet) and it worked.

OK, I got it working about 15 minutes ago. The command succeeds if I
specify the link-local address of the router interface instead of the
ULA address I assigned it:

/sbin/ip -6 route add ::/0 via fe80::206:5bff:fe3e:af91 dev eth1

I am curious to find out if this is intended behavior.

Thanks for the help,

Bill Cerveny
