Unexpected gateway via management interface (in /etc/sysconfig/network) is created whenever a specific management-route is configured using tmsh. This unexpected configuration is applied onto the kernel after a reboot.
An incorrect gateway is configured after a reboot.
This occurs when a specific non-default management-route is configured, and the default management-route is not configured.
You can avoid the issue by configuring a default management-route if you are using non-default management-routes. As a workaround for the issue, delete the unexpectedly created management default route following every reboot. To do so, use a command similar to the following: 'ip route del default dev eth0' or 'ip route del default dev mgmt'. You can include the appropriate command in the file /config/startup to have the command run automatically after each boot operation.
The system uses only the default management-route to configure the gateway If the default management-route is not configured, the system does not create the gateway. This is correct behavior.
