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

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
```

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

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

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
