The next-hop information can be one of the following: network interface, IP host address (local or peer address on point-to-point links), or IP subnet address (of the directly connected subnet for an interface).
Note that observers (NexthopPortMapperObserver) can be attached to monitor changes to the port mapping. The observers notification is triggered by an explicit call to NexthopPortMappernotify_observers.

| int add_observer (NexthopPortMapperObserver* observer)
| add_observer |
Add an observer for observing changes to the mapper.
Parameters:
| observer | the observer to add. |
Returns: XORP_OK on success, otherwise XORP_ERROR.
| int delete_observer (NexthopPortMapperObserver* observer)
| delete_observer |
Delete an observer for observing changes to the mapper.
Parameters:
