[LARTC] Problems with iproute2

[Jan Andersen]

I'm using Debian (sarge)

I do now have 2 ISP, one DSL and one cabel.

I want to use the DSL as my primary and only use the cabel-modem if the DSL
fails.

The setup is:

IP1 -> Router -> NAT_IP1 -> eth0 -> eth2 (LAN)
IP2 -> Cable-Modem       -> eth1 -> eth2 (LAN) 

I wrote the following in my /etc/iproute2/rt_tables

ip rule add from NAT_IP1 lookup 1
ip route add 10.1.0.0/16 via 10.1.1.1 table 1
ip route add 0/0 via NAT_IP1 table 1

ip rule add from IP2 lookup 2
ip route add 10.1.0.0/16 via 10.1.1.1 table 2
ip route add 0/0 via IP2 table 2

The problem is identical to http://www.samag.com/documents/s=1824/sam0201h/

But if I write "ip rule list" I get the following error:

Database /etc/iproute2/rt_tables is corrupted at ip rule add from
192.168.100.254 lookup 1

Does anyone know and have a solution to this problem?
