suse12: how to set default route via config file

Question

I've got some systems that are provisioning SLES12sp1 statelessly - the systems come up with their provisioning interface configured, but no default route.

On RedHat I'd set the GATEWAYDEV in /etc/sysconfig/network -- but I can't find an equivalent for openSUSE/SLES.

There is no NetworkManager or ifcfg files:

# ls /etc/sysconfig/network/
config  dhcp  if-down.d  if-up.d  ifcfg-lo  ifcfg.template  network  providers  scripts

Some additional context:

# ifconfig eth2
eth2      Link encap:Ethernet  HWaddr XX:XX:XX:XX:XX:XX  
          inet addr:192.168.1.29  Bcast:192.168.1.255  Mask:255.255.255.0
          inet6 addr: fe80::21e:67ff:fecb:f26f/64 Scope:Link

# route -n

192.168.1.0      0.0.0.0         255.255.255.0     U     0      0        0 eth2

Solution

Create or edit /etc/sysconfig/network/routes and add a line like :

default 192.168.1.1 - -

(where, in case it would not be obvious, 192.168.1.1 is your gateway)

Have you seen this page? suse.com/documentation/sled11/book_sle_admin/data/…

Yes -- the sle 12 version of that doc, but I haven't found anything in it that resolves my issue.

[John Westlund]

@heritu -- no luck. Tried default <ip> - -, default <ip> - eth2, default - - eth2. Maybe because PXE is bringing up the interface?

[John Westlund]

I think your answer is correct -- but won't work in my case because of how the provisioning is happening.
