I want to add the following route command route add -net 192.168.2.0/27 gw 192.168.2.3 via the normal network setup. The result should be the following routing table (the first line): 192.168.2.0/27 via 192.168.2.3 dev xenbr1 scope link 192.168.2.0/27 dev eth2 proto kernel scope link src 192.168.2.4 192.168.2.0/27 dev xenbr1 proto kernel scope link src 192.168.2.3 192.168.1.0/24 dev xenbr0 proto kernel scope link src 192.168.1.24 default via 192.168.1.1 dev xenbr0 I found: http://www.cyberciti.biz/faq/redhat-centos-fedora-linux-static-routing/ http://www.centos.org/docs/5/html/5.2/Deployment_Guide/s1-networkscripts- static-routes.html tells me to use sysconfig/route-xenbr1 But whatever syntax I try I get a variety of errors: Bringing up interface xenbr1: Error: an inet address is expected rather than "1"..168.2.3 Bringing up interface xenbr1: Error: an inet prefix is expected rather than "19/27"..2.0 Bringing up interface xenbr1: Error: either "to" is duplicate, or "192.168.2.3" is a garbage.
