Router A is unable to reach Router B.Both routers are running ios version 12.0.After reviewing the
command output and graphic,what is the most likely cause of the problem?
A. incorrect bandwidth configuration   
B. incorrect LMI configuration   
C. incorrect map statement   
D. incorrect IP address   
大家看图中这个的这条信息，frame-relay 172.16.100.1 200 broadcost,很明显这个200LMI错了，应该是100才对。我认为选B选项，为什么答案给了一个C选项。我有些不能理解，请大家帮我分析下。

对啊，选项Ｃ就是说frame-relay 172.16.100.1 200 broadcost不合适啊，选项Ｂ意思是ＬＭＩ不匹配，ＬＭＩ默认类型都是Ｃｉｓｃｏ的，一般不会不匹配
