Another way is to dispense with the routing syntax and setup the variables in the file: [root@XXX network-scripts]# cat route-eth0 ADDRESS0=192.168.16.0 ADDRESS1=192.168.17.0 ADDRESS2=192.168.18.0 NETMASK0=255.255.255.0 NETMASK1=255.255.255.0 NETMASK2=255.255.255.0 GATEWAY0=192.168.15.200 GATEWAY1=192.168.15.200 GATEWAY2=192.168.15.200 Red Hat's startup scripts will pattern match base on the variables and file name, setting the routes accordingly per adapter. In this case, the routes in question will be configured through eth0. Here is another example: [root@sl6 network-scripts]# cat route-virbr0 ADDRESS0=192.168.122.0 NETMASK0=255.255.255.0 This setup the routes on the virtual interface to my VMs. Since the gateway is local, there was no need to setup the gateway variable. At any event, here is the output of my routes after bootup: [root@sl6 ~]# netstat -rn Kernel IP routing table Destination Gateway Genmask Flags MSS Window irtt Iface 192.168.18.0 192.168.15.200 255.255.255.0 UG 0 0 0 eth0 192.168.17.0 192.168.15.200 255.255.255.0 UG 0 0 0 eth0 192.168.16.0 192.168.15.200 255.255.255.0 UG 0 0 0 eth0 192.168.15.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0 192.168.122.0 0.0.0.0 255.255.255.0 U 0 0 0 virbr0 169.254.0.0 0.0.0.0 255.255.0.0 U 0 0 0 eth0 0.0.0.0 192.168.15.1 0.0.0.0 UG 0 0 0 eth0 http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5/html/Deployment_Guide/s1-networkscripts-static-routes.html On Jun 7, 2011, at 1:17 PM, Richardson, Joshua A. wrote: > You can simply create the file in the /etc/sysconfig/network-scripts folder.
