Linux Static route modification

1. Method One:

• Add Add route
• del Delete route
• -net setting a route to a network segment
• -host setting a route to a host
• GW Export Gateway IP address
• Dev Egress Gateway Physical device name

• Add route
  • Route add-net 192.168.0.0/24 GW 192.168.0.1
  • Route Add-host 192.168.1.1 Dev 192.168.0.1
• Delete route
  • Route del-net 192.168.0.0/24 GW 192.168.0.1
• Add default route
  • Route add default GW 192.168.0.1
• Route-n Viewing the routing table

Method Two:

• Add Add route
• del Delete route
• Via Gateway egress IP Address
• Dev Gateway Export Physical device name
• Add route
  • IP route add 192.168.0.0/24 via 192.168.0.1
  • IP route add 192.168.1.1 dev 192.168.0.1
• Delete route
  • IP route del 192.168.0.0/24 via 192.168.0.1
• Add default route
  • IP route add default via 192.168.0.1 dev eth0
• Via 192.168.0.1 is my default router
• Viewing routing information
  • IP route
• Save the routing settings so that they are valid after a network restart
  • Create a file named Route-eth0 under the/etc/sysconfig/network-script/directory
  • Vi/etc/sysconfig/network-script/route-eth0
  • Add content in this file in the following format
  • 192.168.1.0/24 via 192.168.0.1
  • Restart network authentication

There are a few lines in/etc/rc.d/init.d/network:

# Add non interface-specific static-routes.
if [-f/etc/sysconfig/static-routes]; Then
grep "^any"/etc/sysconfig/static-routes | While read ignore args; Do
/sbin/route add-$args
Done
Fi

In other words, adding static routes to the/etc/sysconfig/static-routes file is OK.

If you join:
Route add-net 11.1.1.0 netmask 255.255.255.0 GW 11.1.1.1

The format of the static-routes is
Any net 11.1.1.0 netmask 255.255.255.0 GW 11.1.1.1
