 NetworkManager also supports other types like `wifi`, `vpn`, `bridge`, `vlan`, etc. Note that other types than `ethernet` and `ethernet` have so far not been tested. Please contact us if you managed to set up some other network type or need help to do so.
 
+### Static Routes
+
+Static routes can be added with the `additional_config` key in the connection settings.
+Depending on the IP version there is a `ipv4` or `ipv6` subkey which then can contain many `routes` + number keys. So the first route is `routes1`, the second `routes2`, etc.
+The minimal entry for `routesX` is the network and then, separated with a comma, the next hop IP. The optinal third entry is the metric.
+For each route you may also add a option key `routesX_options`, where multiple options in the form `name=value` can be added, again comma separated.
+
+An example:
+
+```
+networking::connection::management_network:
+  interface_name: 'eno1'
+  ipv4_method: 'manual'
+  ipv4_address: '192.168.71.10/24'
+  ipv6_method: 'disabled'
+  additional_config:
+    ipv4:
+      routes1: '10.255.254.0/24,192.168.71.10'
+      routes2: '10.255.255.0/24,192.168.71.10,100'
+      routes2_options: 'lock-cwnd=false,lock-mtu=false'
+```
+
+All routing options can be found in the Red Hat NetworkManager documentation ([RHEL8](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/configuring-static-routes_configuring-and-managing-networking#how-to-use-the-nmcli-command-to-configure-a-static-route_configuring-static-routes), [RHEL9](https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/configuring_and_managing_networking/configuring-static-routes_configuring-and-managing-networking#how-to-use-the-nmcli-command-to-configure-a-static-route_configuring-static-routes)).

 ### DNS Override
 
 The internal nameservers are configured according to the network zone by Puppet.
