案例研究（实验）：远程拨号连接 说明：Router2503通过AUX外接ModemA来接入拨号，ModemB是拨号主机的MODEM，拨号主机通过路由器接受ip地址。拓扑图是最典型的电话远程拨号连接。 用户名：hutnis，密码：cisco ModemA的电话：3355， ModemB的电话：3322 HostA的IP：192.168.10.100/24 Router2503的E0：192.168.10.1/24 Router2503分配地址池192.168.100.25给HostB 连接的默认速度：9600bps -------------------------------------------- 2503#sh run Building configuration...
