The discovery table should be walkable by the NMS. The NMS can walk the entire table or get a specific row using the appropriate key. This is required when the NMS is rebooted or needs to update its entire database.
In addition, every time a node is updated, added, or removed from the OSPF opaque database (using LSA type 10 opaque update) a trap is sent to the NMS to notify the NMS of the change if the configure system network-element-discovery generate-traps command is configured. These traps are:
