Linux can add routing commands using the route command or the ip command. The following describes how to use the two methods:

1. Use the route command:

1. Add a default route:

csharpCopy coderoute add default gw <Gateway IP address> <Network interface>

where< Gateway IP address> is the gateway address of the default route to be added, is the network interface through which the route is to be routed, for example:

csharpCopy coderoute add default gw 192.168.1.1 eth0

2. Add a static route:

phpCopy coderoute add -net <Target network address> netmask <Subnet mask> gw <Gateway IP Address> <Network Interface>

where is the destination network address of the static route to be added, is the subnet of the destination network Netmask, is the gateway address of static routing, is the network interface through which the route is routed, for example:

csharpCopy coderoute add -net 192.168. 2.0 netmask 255.255.255.0 gw 192.168.1.1 eth0

2. Use the ip command:

#1. Add a default route:

csharpCopy codeip route add default via <Gateway IP address> dev <Network interface>

where is the gateway address of the default route to be added, is the network interface through which the route is to be routed, for example:

csharpCopy codeip route add default via 192.168.1.1 dev eth0

2. Add a static Route:

phpCopy codeip route add <Destination Network Address>/<Subnet Mask> via <Gateway IP Address> dev <Network Interface>

Where / is the target network address and subnet mask of the static route to be added, is the gateway address of the static route , is the network interface through which the route is to be routed, for example:

csharpCopy codeip route add 192.168.2.0/24 via 192.168.1.1 dev eth0
