BGP下有如下配置： Timer keep alive 30 hold 30 Peer 1.1.1.2 timer keepalive 10 hold 30 下面哪些描述是错误的（）
A
全局配置优先，所以最终结果是peer 1.1.1.2的timer值取keep alive 30 hold 90
B
Peer配置优先，所以最终结果是peer 1.1.1.2的timer值取keep alive 10 hold 30
C
Timer取最小值，所以最终结果是peer 1.1.1.2的timer值取keep alive 10 hold 30
D
缺省配置为timer keep alive 60 hold 180，故peer 1.1.1.2具有比缺省值更快的检测peer连接故障的速度
