The LDP GR function can also implement nonstop data forwarding, but it requires that the GR restarter
and all its neighbors support LDP GR. With the LDP NSR function, the neighboring devices do not need
to support LDP NSR. They are not aware of any switchover event on the NSR-enabled device.
The LDP GR feature and the LDP NSR feature are mutually exclusive. Do not configure both features on the
device.
To configure LDP NSR:
