Verify interface parameters ``` nmcli connection show <intf name> ``` 4. Reapply network interface configuration ``` nmcli device reapply <intf name> ``` #### Removing existing ip routes To remove existing routes, use the following command: ``` nmcli connection modify <intf name> -ipv4.routes ”<subnet/mask> <next_hop>” ``` ### See also 1. ### Reference 1.
