路由器b的配置如下 quidway#show run current configuration ! user hw service-type ppp password 0 quidway ! interface ethernet0 ip address 3.1.1.1 255.0.0.0 ! interface serial0 clock-select dteclk1 encapsulation ppp ppp chap host huawei ip address 1.1.1.2 255.0.0.0 ! interface serial1 encapsulation ppp ! interface serial2 flowcontrol normal async mode dedicated encapsulation ppp ! exit ip route 0.0.0.0 0.0.0.0 2.1.1.2 preference 60 end 发现两端路由器不能ping同对端以太网端口,下述说法正确的是(bcd ) a、a验证配置错误 b、b验证配置错误 c、a验证方路由配置错误 d、b被验证方路由配置错误 47、路由器a配置如下: quidway#show run now create configuration... current configuration ! ! interface ethernet0 ip address 1.1.1.1 255.0.0.0 ! interface serial0 clock-select dteclk1 encapsulation x25 dte ietf x25 address 2111 x25 map ip 2.1.1.2 2112 ip address 2.1.1.1 255.0.0.0 ! interface serial1 encapsulation ppp ! interface serial2 flowcontrol normal async mode dedicated encapsulation ppp ! exit router rip ! end 路由器b配置如下 quidway#show run now create configuration... current configuration ! ! interface ethernet0 ip address 3.1.1.1 255.0.0.0 ! interface serial0 encapsulation x25 dce ietf x25 address 2112 x25 map ip 2.1.1.1 2111 ip address 2.1.1.2 255.0.0.0 ! interface serial1 encapsulation ppp ! interface serial2 flowcontrol normal async mode dedicated encapsulation ppp ! exit router rip ! end 如下说法正确的是( a) a、两端广域网可以联通,但局域网不可以连通 b、两端广域网不可以连通,但局域网可以连通 c、广域网和局域网都可以连通 d、广域网和局域网都不能连通 |
