Load Balancing with secondary tables (not main as in the howto)

Linux Advanced Routing and Traffic Control

Hello,

 

      We have 3 DSL connections connected to eth3 and another interface with a dedicated link in eth0 (main table)

 

We want to balance selected traffic (using fwmark and iptables) through our 3 DSL connections in a secondary table named DSL (without using the dedicated link in eth0), but the next command is not accepted, and gives us the following error:

 

 

# ip route add default scope global nexthop via 10.0.1.1 dev eth3 weight 1 nexthop via 10.0.2.1 dev eth3 weight 3 nexthop via 10.0.3.1 dev eth3 weight 2 table DSL

Error: "nexthop" or end of line is expected instead of "table"

 

 

 

That because the syntax rules of ip:

 

# ip route add help

Usage:

       ip route { add | del | change | append | replace | monitor } ROUTE

SELECTOR := [ root PREFIX ] [ match PREFIX ] [ exact PREFIX ]

            [ table TABLE_ID ] [ proto RTPROTO ]

            [ type TYPE ] [ scope SCOPE ]

ROUTE := NODE_SPEC [ INFO_SPEC ]

NODE_SPEC := [ TYPE ] PREFIX [ tos TOS ]

             [ table TABLE_ID ] [ proto RTPROTO ]

             [ scope SCOPE ] [ metric METRIC ]

INFO_SPEC := NH OPTIONS FLAGS [ nexthop NH ]...

NH := [ via ADDRESS ] [ dev STRING ] [ weight NUMBER ] NHFLAGS

 

 

The question is, can I add load balancing over a secondary table in any other way? Why ip route add doesn’t allow this?

 

Thanks in advance.

 

 

Note:

 

- Architecture:

 

     

        Linux box ---- eth3 --------------- | ----- ADSL1 (IP: 10.0.1.1)

            |                               | ----- ADSL2 (IP: 10.0.2.1)

|                               | ----- ADSL3 (IP: 10.0.3.1)

     eth0

     

 

 

# ip addr show dev eth3

5: eth3: <BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast qlen 1000

    link/ether 00:16:17:9d:3d:b2 brd ff:ff:ff:ff:ff:ff

    inet 10.0.1.2/24 brd 10.255.255.255 scope global eth3

    inet 10.0.2.2/24 brd 10.255.255.255 scope global eth3:1

    inet 10.0.3.2/24 brd 10.255.255.255 scope global eth3:2
