Routing function configurationIn actual production we can also configure the Linux system as a router.As shown, a total of 5 hosts, the middle R1,r2,r3 three as a router to use. First we configure the relevant IP addresses for 5 hosts.1. Turn on the routing featureTo see if the routing feature is turned on: Cat/proc/sys/net/ipv4/ip_forward 1 for open,

How does the CentOS server add permanent static routes? One, Linux add permanent static route Method One: Modify the rc.local configuration file Scope: Test Ubuntu 14.04, CentOS 6.4, Debian 8.1, Redhat 6.4 system available How to use: 1. Add a command to the/etc/rc.local file in the Linux system Route add-net 192.168.2.0/24 GW 192.168.2.254 (the default route for the server is 192.168.2.254), or add a command route Add-net 192.168.3.0/24 Dev Eth0
