Example methods and apparatus to monitor tunnels within traffic engineering/fast reroute (TE/FRR) enabled networks are disclosed. A disclosed example apparatus includes a message interface to receive from a router a change alert notification for a traffic engineering (TE) tunnel, a router interrogator to interrogate the router to obtain updated path information for the TE tunnel in response to the received change alert notification, and a topology database interface to update a database representative of a tunnel topology of a TE/FRR enabled network based on the updated path information.
