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.
