Details

It may be useful to be able to define static routes within netcfg.

Considering the migration to iproute2, the additional syntax could be as simple as
ROUTES=("192.168.1.0/24 via 192.168.0.1" "192.168.2.0/24 via 192.168.0.2")

which would translate as commands
ip route add 192.168.1.0/24 via 192.168.0.1 dev $INTERFACE
ip route add 192.168.2.0/24 via 192.168.0.2 dev $INTERFACE

(This assumes that network 192.168.0.0/24 is reachable via $INTERFACE, which is currently being configured)

Similarly for IPv6 (see  FS#18699 ),
ROUTES=("2001:DB8:1::/64 via 2001:DB8:1::1")
would translate to
ip -6 route add 2001:DB8:1::/64 via 2001:DB8:1::1 dev $INTERFACE
This task depends upon

Reason for closing:  Implemented
Additional comments about closing:  Merged in git except that it will only happen if IP='static'

Typo: instead of
ROUTES=("2001:DB8:1::/64 via 2001:DB8:1::1")
I meant
ROUTES6=...
for coherence.

Oh well. It is as fast to code it myself (;

This patch adds netcfg configuration option "ROUTES" to setup static routes. This is done
regardless of whether the IP address is configured using a DHCP or statically.
ROUTES is an array containing entries of the form "DESTINATION[/NETMASK] [via
ROUTER]" which are directly used in an “ip route add” command.

First, a small correction of the previous patch.

Then, the IPv6 version. I realise after looking at the code that this could have been done using the IPCFG (and IP6CFG from  FS#18699 ) parameter, and this proposal is just a generalisation of the GATEWAY parameter. Anyway, here is the code.

Please excuse me for the mess with the order of the patches.
