Hello, There is SUSE Linux Enterprise Server 15 SP1 server which has following network interface **eth0 171.16.10.10 eth1 171.16.20.10 eth2 171.16.30.10 eth3 171.16.40.10** I want to setup the static root as following. **171.16.130.0/24 via 171.16.0.1 dev eth0 171.16.140.0/24 via 171.16.0.1 dev eth1 171.16.150.0/24 via 171.16.0.1 dev eth2 171.16.160.0/24 via 171.16.0.1 dev eth3** I referred to the Administration Guide([https://documentation.suse.com/sles/15-SP1/html/SLES-all/cha-network.html](https://documentation.suse.com/sles/15-SP1/html/SLES-all/cha-network.html)) “19.4.1.5 Configuring Routing”, and setup as following. ![](https://forums.suse.com/uploads/editor/t5/8p0ww2w53w6t.png) After rebooting the machine I checked the route. But the static roots don’t reflect as following. **ip-171-16-10-10:~ # ip r default via 171.16.0.1 dev eth0 proto dhcp default via 171.16.0.1 dev eth1 proto dhcp metric 10100 default via 171.16.0.1 dev eth2 proto dhcp metric 10200 default via 171.16.0.1 dev eth3 proto dhcp metric 10300 171.16.0.0/17 dev eth2 proto kernel scope link src 171.16.20.10 171.16.0.0/17 dev eth0 proto kernel scope link src 171.16.10.10 171.16.0.0/17 dev eth3 proto kernel scope link src 171.16.40.10 171.16.0.0/17 dev eth1 proto kernel scope link src 171.16.30.10** Next I referred to the same Guid “19.5.2.7 /etc/sysconfig/network/routes and /etc/sysconfig/network/ifroute-”, and setup as following. \*\*\*\*ip-171-16-10-10:~ # cat /etc/sysconfig/network/routes default 171.16.0.1 - eth0 171.16.130.0 171.16.0.1 255.255.255.0 eth0 171.16.140.0 171.16.0.1 255.255.255.0 eth1 171.16.150.0 171.16.0.1 255.255.255.0 eth2 171.16.160.0 171.16.0.1 255.255.255.0 eth3 ip-171-16-10-10:~ # cat /etc/sysconfig/network/ifroute-eth0 171.16.130.0/24 171.16.0.1 - eth0 default 171.16.0.1 - eth0 ip-171-16-10-10:~ # ip-171-16-10-10:~ # cat /etc/sysconfig/network/ifroute-eth1 171.16.140.0/24 171.16.0.1 - eth1 ip-171-16-10-10:~ # ip-171-16-10-10:~ # cat /etc/sysconfig/network/ifroute-eth2 171.16.150.0/24 171.16.0.1 - eth2 ip-171-16-10-10:~ # ip-171-16-10-10:~ # cat /etc/sysconfig/network/ifroute-eth3 171.16.160.0/24 171.16.0.1 - eth3\*\*\*\* After rebooting the machine I checked the route.

I found another problem. I set the routing in YaST. ![](https://forums.suse.com/uploads/editor/di/a505jxotoal0.png) It seems to be set, but unreachable. ![](https://forums.suse.com/uploads/editor/oc/2wzjrqaaofby.png) ---

Hello, If the static route is set, is it impossible to communicate to other subnets? Now it seems to be impossible to communicate 171.16.10.0/24 to 171.16.130.0/24, and so on.
