选项 A、        The broadcast option allows packets,such as RIP updates,to be forwarded access the PVC.

D、        The ip address 10.121.16.8 is the local router port used to forward date.
E、        This command is required for all Frame Rely configurations

答案A

解析 默认情况下帧中继是非广播多路访问网络,意味着不发送广播消息。所以映射语句后面要加broadcast参数来支持广播,这样RIP更新才能在PVC上发送。
