实验一. 路由器IP地址配置及直连网络

实验目的

• 理解IP地址
• 掌握路由器端口IP 地址的配置方法
• 理解路由器的直连网络

实验步骤

1. 布置拓扑，通过GigabitEthernet0/0/0端口连接192.168.1.0/24（手动改），通过GigabitEthernet0/0/1端口连接192.168.2.0/24（指令改）

   Router(config)#interface GigabitEthernet0/0/1
   Router(config-if)#ip address 192.168.2.254 255.255.255.0
   Router(config-if)#no shutdown

2. 查看路由表，C打头的是直连网络

   Router(config-if)#do show ip route
   Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
          D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
          N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
          E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
          i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
          * - candidate default, U - per-user static route, o - ODR
          P - periodic downloaded static route
   
   Gateway of last resort is not set
   
        192.168.1.0/24 is variably subnetted, 2 subnets, 2 masks
   C       192.168.1.0/24 is directly connected, GigabitEthernet0/0/0
   L       192.168.1.254/32 is directly connected, GigabitEthernet0/0/0
        192.168.2.0/24 is variably subnetted, 2 subnets, 2 masks
   C       192.168.2.0/24 is directly connected, GigabitEthernet0/0/1
   L       192.168.2.254/32 is directly connected, GigabitEthernet0/0/1
   

3. 查看端口信息

   Router(config-if)#do show interface GigabitEthernet0/0/1
   GigabitEthernet0/0/1 is up, line protocol is up (connected)
     Hardware is ISR4331-3x1GE, address is 0090.21a5.e802 (bia 0090.21a5.e802)
     Internet address is 192.168.2.254/24
     MTU 1500 bytes, BW 1000000 Kbit, DLY 100 usec,
        reliability 255/255, txload 1/255, rxload 1/255
     Encapsulation ARPA, loopback not set
     Keepalive not supported
     output flow-control is on, input flow-control is on
     ARP type: ARPA, ARP Timeout 04:00:00, 
     Last input 00:00:08, output 00:00:05, output hang never
     Last clearing of "show interface" counters never
     Input queue: 0/375/0 (size/max/drops); Total output drops: 0
     Queueing strategy: fifo
     Output queue :0/40 (size/max)
     5 minute input rate 0 bits/sec, 0 packets/sec
     5 minute output rate 0 bits/sec, 0 packets/sec
        0 packets input, 0 bytes, 0 no buffer
        Received 0 broadcasts (0 IP multicasts)
        0 runts, 0 giants, 0 throttles
        0 input errors, 0 CRC, 0 frame, 0 overrun, 0 ignored
        0 watchdog, 1017 multicast, 0 pause input
        0 input packets with dribble condition detected
   

4. 验证连通性

   从主机端使用ping命令来测试网络的连通性。

   发现没有ping通。

   这时我们给两台PC机加上网关
