How To Persist ip Rule And Route Whenever Server Rebooted?
Clash Royale CLAN TAG#URR8PPP
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty margin-bottom:0;
I'm using Centos 7 Server And I Would Like To Save ip Rule And Route Whenever Server Rebooted.
ip rule add from x.x.x.x table 128
ip route add table 128 to y.y.y.y/y dev eth0
ip route add table 128 default via z.z.z.z
The mentioned Rule and Route lose once i reboot the server which means i need to run the 3 commands each time server rebooted.
I need to make ip rule and route persist whenever server is rebooted.

Take a look at /etc/rc.d/rc.local. The file states, "Please note that you must run 'chmod +x /etc/rc.d/rc.local' to ensure that this script will be executed during boot." So...
chmod +x /etc/rc.d/rc.local
Then place your commands above the last line, touch /var/lock/subsys/local.
There is better way using relevant configuration files. Rules and routes can be specified using corresponding file names. All the relevant configuration files are given below. (The device names may differ.)
/etc/iproute2/rt_tables
/etc/sysconfig/network
/etc/sysconfig/network-scripts/ifcfg-eth0
/etc/sysconfig/network-scripts/ifcfg-eth1
/etc/sysconfig/network-scripts/route-eth0
/etc/sysconfig/network-scripts/route-eth1
/etc/sysconfig/network-scripts/rule-eth0
/etc/sysconfig/network-scripts/rule-eth1
To create a named routing table, use /etc/iproute2/rt_tables. I added 128 mynet.
#
# reserved values
#
255 local
254 main
253 default
0 unspec
#

128 mynet
