C的答案说：The route 10.10.23.3 is not being advertised to other BGP neighbors.
这明显不对
这条路由通告给10.10.23.3了呢，如果不通告其它的邻居应该是这样的
Not advertised to any peer

这条路 ...

这条路由不是从10.10.23.3学到的？怎么又会向它宣告呢？

大冰块

楼主你这样理解就明白了，C答案的意思是10.10.23.3这条路由没有被宣告给其他BGP邻居，但是题目给的是6.6.6.0这条路由，根本没有办法判断10.23.3.3是否被宣告给其他邻居，当然不选。如果要选C，那题目也必须给出show ip bgp 10.10.23.3 的信息才行。
