3. 如图, RTA 、 RTB 、 RTC 运行 OSPF ,进程号为 100 ； RTA 、 RTB 、 RTD 间运行 OSPF 进程 200 。所有互联链路的 cost 都设置为 10 。在 RTA 和 RTB 上设置 OSPF 100 的外部路由优先级为 190 ,在 RTC 上将一条外部路由 172.16.1.0/24 引入 OSPF100 。 RTA 设置将 OSPF100 的路由引入到 OSPF200 , RTB 上设置将 OSPF200 的路由重新引入到 OSPF100 。运行稳定后假设 RTC 上引入外部路由 172.16.1.0/24 突然消失。
根据以上场景分析,下面描述正确的是 ______ 。

A) RTD 上 172.16.1.0/24 的路由仍旧存在,下一跳指向 RTA
B) RTC 上 172.16.1.0/24 的路由仍旧存在,下一跳指向 RTB
C) RTD 上 172.16.1.0/24 的路由消失
D) RTC 上 172.16.1.0/24 的路由消失

4. OSPF TotallNSSA 区域中肯定不会注入 ______ 类型的 LSA 。

A) Tpe7
B) Tpe5
C) Tpe4
D) Tpe3
