During a recent OSPF election among three routers, RTA was elected the DR and RTB was elected the BDR, as seen in the graphic. Assume that RTA fails, and that RTB takes the place of
the DR whi le RTC becomes the new BDR. What will happen when RTA comes back online？（）

下面是路由器RTA的部分配置：
[RTA-ospf-100]ospf 100
[RTA-ospf-100]silent-interface gigabitethernet1/0/0
对于此部分配置描述错误的是（）

在MSR路由器RTA上执行displaospfvlink命令，路由器输出如下：
OSPFProcess100withRouterID3.3.3.3
VirtualLinks 
Virtual-linkNeighbor-ID->2.2.2.2，Neighbor-State：FullInterface：20.0.0.1（GigabitEthernet0/1）
Cost:1State：P-2-PTpe：VirtualTransitArea：0.0.0.1
Timers：Hello10，Dead40，Retransmit5，TransmitDela1
从以上输出可以判断（）。
