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

In which two ways does the BGP graceful capability preserve prefix information during a restart？（）A、The peer router immediately removes the BGP routers that it learned from the restarting router from itsBGP routing tables.B、The router establishes BGP sessions with other routers and relearns the BGP routes from others that are also capable of graceful restart.
