    BGP runs over a reliable transport （ ）. This eliminates the need to implement explicit update fragmentation, retransmission, acknowledgement, and （请作答此空）. Any authentication scheme used by the transport protocol may be used in addition to BGP's own （ ）mechanisms. The error notification mechanism used in BGP （ ）that the transport protocol supports a “graceful” close, i.e., that all outstanding data will be delivered （ ）the connection is closed.

    A.synchronization
    B.conflict

    答案：D
    解析：
    bgp通过可靠的传输协议运行。这样就不需要实现显式的更新分段、重新传输，确认和排序。使用的任何身份验证方案除了bgp自己的身份验证机制之外，还可以使用传输协议的验证方案。bgp中采用的错误通知机制，假定传输协议支持“正常”关闭，也就是说，所有未完成的数据将在连接关闭之前交付。
