1. Add a route table
Route add 60.232.142.40 mask 255.255.255.248 192.168.100.250 Metric
3 if
2
Add a route record. All data packets destined for the 60.232.142.40/29 CIDR block go through the gateway of 192.168.100.250 through the interface card No. 2. The priority is 3. (What will happen ?)
Route
Add-P 60.232.142.40 mask 255.255.255.248 192.168.100.250 metric 3 if
2
It works the same as above, but it is a long-term route and will not be lost because of restarting the machine.
2. delete a route table
Route Delete
60.232.142.40
NOTE: If two route records have the same "destination network number", the two records will be deleted at the same time. If you only want to delete one of them, use Route
Add another one to the Add command.

3. modify a route record
Route
Change 157.0.0.0 mask 255.0.0.0 157.55.80.5 metric 2 if
2
The change parameter can only be changed to "Gateway" and "hop count" Linux to add route routes.
| Adding a Linux route is very important for us. Sometimes the network is disconnected. Maybe you did not add or release the route. I hope it will help you! Server IP (eth0)

The meaning of each field in the output result is:
Destination indicates the destination IP address of the route
Gateway indicates the host name or IP address used by the gateway. The output "*" indicates that no gateway exists.
Genmask indicates the network mask of the route
Flags indicates a route entry. The available flag indicates that the route is starting. h indicates that the target is a host, G indicates that the gateway is used, r indicates that the dynamic route is reset. D indicates that the route is dynamically installed, M indicates modifying the route ,! Indicates that the route is denied.
Metric indicates the sales volume of the route.
Ref indicates the number of other routes that depend on the current status of the current route.
Use indicates the number of route table entries used.
Iface indicates the destination network for the packet sent by the route to be transferred from: http://lzhxiaoyu.blog.51cto.com/10707/291323 |
