What are the steps for configuring static routes in Linux?

The steps to configure static routes in a Linux system are as follows:

1. Open the terminal and log in with administrator privileges (you can use the sudo or su command).
2. Use the ‘route’ or ‘ip route’ command to check the routing table of the current system and confirm the current routing situation.
3. To add a static route using the ip route add command, the syntax is: ip route add destination network/subnet mask via next hop IP address. For example, ip route add 192.168.1.0/24 via 192.168.0.1.
4. To delete a static route, you can use the “ip route del” command with the syntax “ip route del via “. For example: “ip route del 192.168.1.0/24 via 192.168.0.1”.
5. Use the “ip route” command to check the updated routing table and confirm whether the static routes have been correctly added or removed.
6. Static routes configuration can be permanently saved using a configuration file, with the file path usually being /etc/sysconfig/network-scripts/route-eth0 (the exact path may vary depending on the system version).

Please note: Static routes are manually configured routes that need to be manually added and deleted, and they are lost after a system reboot. If you need permanent route configurations, consider using dynamic routing protocols.
