Support for route leaking when device is in overload mode

You can enable a device to leak route information to the network even if the overload mode has been configured on your device. To enable your device to leak route information, include the allow-route-leaking option when you specify the overload statement at the [edit protocols isis] hierarchy level. Note that route leaking will not work if the device is in dynamic overload mode, when the device resources such as the prefix limit, have been exceeded.
