• In the following essay, each blank has four choices. Choose the best answer and write down on the answer sheet.

  In low-speed network,it is usually adequate to wait for congestion to occur and then react to it by telling the source of packets to slow down. In high-speed networks, this approach often works poorly, because in the (71) between sending the notification and notification arriving at the source, thousands of additional (72) may arrive. In ATM network , a major tool for preventing (73) is (74) control. When a host wants a new virtual (75) ,it must describe the traffic to be offered and the service expected.

  试题一:(15分)

  某网络的连接于图1所示,其路由器的配置如下。

  【路由器Router的部分配置信息】

  Router(config)#interface fastEthernet1/0.1

  Router(config-subif)#encapsulation isl 11 (1)

  Router(config-subif)#ip address 10.1.1.1 255.255.255.0 (2)

  Router(config-subif)#exit

  Router(config)# interface fastEthernet1/0.2

  Router(config- subif)#encapsulation isl 12

  Router(config- subif)#ip address 10.1.2.1 255.255.255.0

  Router(config-subif)#exit

  Router(config)# interface fastEthernet1/0.3

  Router(config- subif)#encapsulation isl 13

  Router(config- subif)#ip address 10.1.3.1 255.255.255.0

  Router(config-subif)#exit

  Router(config)# ip routing (3)

  【交换机Switch1的部分配置信息】

  Switch1(config)#vlan database (4)

  Switch1(vlan)#vlan 11 (5)

  Switch1(vlan)#vlan 12

  Switch1(vlan)#vlan 13

  Switch1(vlan)#exit

  Switch1(config)#interface fastEthernet0/0

  Switch1(config-if)#switchport mode trunk(6)

  Switch1(config-if)#switchport trunk allowed all (7)

  Switch1(config-if)#exit

  Switch1(config)#interface fastEthernet0/1

  Switch1(config-if)#switchport mode trunk

  Switch1(config-if)#switchport trunk allowed all

  Switch1(config-if)#exit

  Switch1(config)#interface fastEthernet0/2

  Switch1(config-if)#switchport mode trunk

  Switch1(config-if)#switchport trunk allowed all

  Switch1(config-if)#exit
【问题1】

  解释画线部分的意义。(7分)

  答: (1)将vlan11 的接口封装为ISL(2)设置vlan1的默认网关为10.1.1.1 (3)启动ip转发 (4)定义vlan (5)定义一个vlan 为11 (6)接口设置为trunk模式 (7)允许所有vlan信息在trunk中传递

  【问题2】

  给出三个vlan各自的IP地址范围。(3)

  vlan11 10.1.1.0/24 vlan12 10.1.2.0/24 vlan13 10.1.3.0/24

  【问题3】

  若不采用路由器,全部采用交换机实现,是否可行?给出解释。

  答:可以,一台交换机具有路由模块(或支持三层交换),作为中心交换机。
