No, my internal network is configured statically through GUI. Ok, then I would just remove the default gateway config on em1 for your master node. Using three cmds: systemctl stop NetworkManager , and systemctl disable NetworkManager , then reboot.

The problem is solved. Now I only have one default gateway belongs to em4. This is equivalent to what you said. However, my network service cannot startup. Static Routes and the Default Gateway.

Static routes are for traffic that must not, or should not, go through the default gateway. Routing is often handled by devices on the network dedicated to routing although any device can be configured to perform routing. Therefore, it is often not necessary to configure static routes on Red Hat Enterprise Linux servers or clients.

Exceptions include traffic that must pass through an encrypted VPN tunnel or traffic that should take a specific route for reasons of cost or security. The default gateway is for any and all traffic which is not destined for the local network and for which no preferred route is specified in the routing table. The default gateway is traditionally a dedicated network router. Back in the Network window, disable and re-enable the connection by switching the button for the connection to Off and back to On for changes to take effect.

You can use the nm-connection-editor application to add a static route to the configuration of a network connection. Open a terminal and enter nm-connection-editor :.

Click the Add button and enter the address, netmask, gateway, and optionally a metric value. Restart the network connection for changes to take effect. For example, to restart the example connection using the command line:. You can use the interactive mode of the nmcli utility to add a static route to the configuration of a network connection. Open the nmcli interactive mode for the example connection:.

The ip attribute displays the network to route and the nh attribute the gateway next hop. When you restart the connection, all connections currently using this connection will be temporarily interrupted. You can add a static route to the configuration of a network connection using the nmstatectl utility. When you run a play that uses the networking RHEL System Role, the System Role overrides an existing connection profile with the same name if the settings do not match the ones specified in the play.

Therefore, always specify the whole configuration of the network connection profile in the play, even if, for example, the IP configuration already exists. Otherwise, the role resets these values to their defaults. Depending on whether it already exists, the procedure creates or updates the enp7s0 connection profile with the following settings:.

To connect as root user to the managed host, enter:. This procedure describes how to manually create a routing configuration file for an IPv4 route to the In this example, the corresponding gateway with the IP address The legacy network scripts support the key-value-format only for static IPv4 routes. For IPv6 routes, use the ip -command-format. See Creating static routes configuration files in ip-command-format when using the legacy network scripts.

If you add multiple static routes, increase the number in the variable names. Note that the variables for each route must be numbered sequentially. This procedure describes how to manually create a routing configuration file for the following static routes when you use legacy network scripts:. The example in this procedure uses configuration entries in ip -command-format.
