To configure static routes using the nmcli tool, use one of the following:
  • the nmcli command line
  • the nmcli interactive editor

Example 4.1. Configuring Static Routes Using nmcli

To configure a static route for an existing Ethernet connection using the command line:
~]# nmcli connection modify eth0 +ipv4.routes "192.168.122.0/24 10.10.10.1"
This will direct traffic for the 192.168.122.0/24 subnet to the gateway at 10.10.10.1
