Abstract
Method and apparatus for detecting whether router status information sent from a first router is unreliable, includes structure and/or steps for storing a router status database. Structure and/or steps are provided for receiving a first signal corresponding to a first router status message sent by the first router, the first router status message containing router status information indicative of the status of communication between the first router and a second router. Further, structure and/or steps are provided for issuing an alarm signal if the signal comparison reveals that the first and second router status messages contain non-complementary router status information. Such information can be flooded through the network to isolate the unreliable/compromised router.
