swerAC解释一下:在VTY线路下应用ACL,可以控制从VTY线路进来的tel
et的流量。也可以过滤穿越一台路由器的流量。2AdefaultFrameRelayWANisclassifiedaswhattypeofphysical

swerC解释一下:在默认的情况下,帧中继为非广播多路访问链路。但是也可以通过子接口来修改他的网络的类型。3.RefertotheexhibitHowma

swerC解释一下:广播域的问题,在默认的情况下,每个交换机是不能隔离广播域的,所以在同一个区域的所有交换机都在同一个广播域中,但是为了减少广播的危害,将广播限制在一个更小的范围,有了VLAN的概念,VLAN表示的是一个虚拟的局域网,而他的作用就是隔离广播。所以被VLAN隔离了的每个区域都表示一个单独的广播域,这样一个VLAN中的广播的流量是不能传到其他的区域的,所以在上题中就有3个广播域了。

swerE解释一下:关于命令framerelaymapip10121168102broadcast这个命令用于手工静态添加一条映射,到达10121168的流量封装一个DLCI号为102,而且这条PVC是支持广播的流量的,比如RIP的更新包。因为在默认的情况下,帧中继的网络为非广播r
