  • Methods and apparatus to monitor border gateway protocol sessions
    Patent number: 8948021
    Abstract: Example methods and apparatus to monitor border gateway protocol sessions are disclosed. A disclosed example method includes detecting a failure of a first BGP session, initiating a sustained-down timer and a reset-timer in response to detecting the failure, identifying a sustained-down condition in response to the sustained-down timer exceeding a first time threshold, identifying a flapping condition in response to counting a threshold number of BGP failures and corresponding BGP re-establishments during a second time threshold of the reset-timer, and identifying a continuous flapping condition in response to detecting the flapping condition consecutively for a threshold number of instances.

  • Methods and apparatus to monitor border gateway protocol sessions
    Patent number: 8169921
    Abstract: Example methods and apparatus to monitor border gateway protocol sessions are disclosed. A disclosed example method includes detecting a failure of a first border gateway protocol (BGP) session and initiating a session-down timer in response to detecting the failure. The example method also includes generating a sustained-down alarm when a threshold time value of the session-down timer is exceeded before the first BGP session is re-established.
