How does linux delete a route
Routes can be deleted using the route command in linux.
1. Command format:
Route [- f] [- p] [Command [Destination] [mask Netmask] [Gateway] [metric Metric]] [if Interface]]
2. Command function:
The Route command is used to manipulate the kernel-based ip routing table, and its main purpose is to create a static route to specify a host or network through a network interface, such as eth0. When the "add" or "del" parameters are used, the routing table is modified, and if there are no parameters, the current contents of the routing table are displayed.
3. Command parameters:
-c display more information
-n does not resolve the name
-v displays detailed processing information
-F display sending message
-C displays the route cache
-f clears the routing table for all gateway entrances.
-p makes the route permanent when used with the add command.
Examples are as follows:
Delete route route del-net 192.168.0.0According to 24 gw 192.168.0.1
Add add route del delete route-net set route to a network segment-host set route to a host gw egress gateway IP address dev egress gateway physical device name
