1.0

1.路由配置IP地址

路由为AR2220

AR2

<Huawei>SY
Enter system view, return user view with Ctrl+Z.
[Huawei]INT	
[Huawei]interface ip	
[Huawei]interface g0/0/0
[Huawei-GigabitEthernet0/0/0]1ip ad	
[Huawei-GigabitEthernet0/0/0]ip	
[Huawei-GigabitEthernet0/0/0]ip ad	
[Huawei-GigabitEthernet0/0/0]ip address 192.168.1.1 255.255.255.0
[Huawei-GigabitEthernet0/0/0]
Sep 18 2024 16:13:25-08:00 Huawei %%01IFNET/4/LINK_STATE(l)[1]:The line protocol
 IP on the interface GigabitEthernet0/0/0 has entered the UP state.

AR2

<Huawei>
Sep 18 2024 16:05:27-08:00 Huawei %%01IFPDT/4/IF_STATE(l)[0]:Interface GigabitEt
hernet0/0/0 has turned into UP state.
<Huawei>sy
Enter system view, return user view with Ctrl+Z.
[Huawei]in	
[Huawei]infa	
[Huawei]infac	
[Huawei]inface ip	
[Huawei]inface 
        ^
Error: Unrecognized command found at '^' position.
[Huawei]
[Huawei]in	
[Huawei]interface g0/0/0
[Huawei-GigabitEthernet0/0/0]ip ad	
[Huawei-GigabitEthernet0/0/0]ip address 192.168.1.2 255.255.255.0
[Huawei-GigabitEthernet0/0/0]
Sep 18 2024 16:10:01-08:00 Huawei %%01IFNET/4/LINK_STATE(l)[1]:The line protocol
 IP on the interface GigabitEthernet0/0/0 has entered the UP state.

然后ping一下看一下是否能ping通

2.DHCP配置

在没有配置dhcp时不会自动分配地址的

接下来开始开启dhcp

<Huawei>sy
Enter system view, return user view with Ctrl+Z.
[Huawei]dhc	
[Huawei]dhcp en	
[Huawei]dhcp enable 
Info: The operation may take a few seconds. Please wait for a moment.done.
[Huawei]int	
[Huawei]int g0/0/0                  #路由接口配置的是0/0/0
[Huawei-GigabitEthernet0/0/0]dhcp	
[Huawei-GigabitEthernet0/0/0]dhcp sel	
[Huawei-GigabitEthernet0/0/0]dhcp select in	
[Huawei-GigabitEthernet0/0/0]dhcp select interface 
[Huawei-GigabitEthernet0/0/0]

接下来在pc端选择dhcp，然后查看ip

3.DNS域名系统

用dns实现域名解析

(网关暂不设置后面再来)

2.在路由里面配置dns

[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]dhcp ser	
[Huawei-GigabitEthernet0/0/0]dhcp server dn	
[Huawei-GigabitEthernet0/0/0]dhcp server dns-list 192.168.1.100          # server服务器配置的ip地址为192.168.1.100
[Huawei-GigabitEthernet0/0/0]

然后就可以直接用域名方式来ping

4.路由技术基础

通过网关去链接100.100.100.100

[Huawei]int g0/0/1                #因为100这个连接的是ge0/0/1这个接口所以在这个接口配置
[Huawei-GigabitEthernet0/0/1]ip add 100.100.100.1 255.255.255.0
[Huawei-GigabitEthernet0/0/1]
Sep 18 2024 16:51:39-08:00 Huawei %%01IFNET/4/LINK_STATE(l)[0]:The line protocol
 IP on the interface GigabitEthernet0/0/1 has entered the UP state.

现在配置完了可以通过192.pc端去ping100

路由器连接多个端口是怎么判断的

路由器有个判断机制是通过路由表来的

Huawei]display ip routing-table 
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Tables: Public
         Destinations : 10       Routes : 10       

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

  100.100.100.0/24  Direct  0    0           D   100.100.100.1   GigabitEthernet
0/0/1
  100.100.100.1/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/1
100.100.100.255/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/1
      127.0.0.0/8   Direct  0    0           D   127.0.0.1       InLoopBack0
      127.0.0.1/32  Direct  0    0           D   127.0.0.1       InLoopBack0
127.255.255.255/32  Direct  0    0           D   127.0.0.1       InLoopBack0
    192.168.1.0/24  Direct  0    0           D   192.168.1.1     GigabitEthernet
0/0/0
    192.168.1.1/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/0
  192.168.1.255/32  Direct  0    0           D   127.0.0.1       GigabitEthernet
0/0/0
255.255.255.255/32  Direct  0    0           D   127.0.0.1       InLoopBack0

可以通过指定ip来查看想要的那个

[Huawei]display ip routing-table 100.100.100.100
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Table : Public
Summary Count : 1
Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

  100.100.100.0/24  Direct  0    0           D   100.100.100.1   GigabitEthernet
0/0/1

5.0小总结

1.电脑开机，通过dhcp获取ip地址

2.电脑输入域名，www.baidu.com 电脑吧 域名发到dns服务器进行解析

3.dns服务器把请求的域名解析成对应ip地址

4.电脑向服务器发送一个请求

2.0

1.静态路由

PC：

路由R1（配置接口0和1）：

<Huawei>sy
Enter system view, return user view with Ctrl+Z.
[Huawei]int g0/0/0
[Huawei-GigabitEthernet0/0/0]ip add 192.168.1.10 255.255.255.0
[Huawei-GigabitEthernet0/0/0]
Sep 18 2024 17:15:22-08:00 Huawei %%01IFNET/4/LINK_STATE(l)[0]:The line protocol
 IP on the interface GigabitEthernet0/0/0 has entered the UP state. 
[Huawei-GigabitEthernet0/0/0]q
[Huawei]sys	
[Huawei]sysname R1
[R1]int g0/0/1
[R1-GigabitEthernet0/0/1]ip add 192.168.2.1 255.255.255.0
[R1-GigabitEthernet0/0/1]
Sep 18 2024 17:17:57-08:00 R1 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP 
on the interface GigabitEthernet0/0/1 has entered the UP state.

路由R2:

<Huawei>sy
Enter system view, return user view with Ctrl+Z.
[Huawei]sys	
[Huawei]sysname R2
[R2]int g0/0/0
[R2-GigabitEthernet0/0/0]ip add 192.168.2.10 255.255.255.0
[R2-GigabitEthernet0/0/0]
Sep 18 2024 17:20:59-08:00 R2 %%01IFNET/4/LINK_STATE(l)[0]:The line protocol IP 
on the interface GigabitEthernet0/0/0 has entered the UP state. 
[R2-GigabitEthernet0/0/0]int g0/0/1
[R2-GigabitEthernet0/0/1]ip add 192.168.3.1 255.255.255.0
[R2-GigabitEthernet0/0/1]
Sep 18 2024 17:21:42-08:00 R2 %%01IFNET/4/LINK_STATE(l)[1]:The line protocol IP 
on the interface GigabitEthernet0/0/1 has entered the UP state. 
[R2-GigabitEthernet0/0/1]q #退出
<R2> save   #保存

server：

现在互相ping不同的

通过数据包传递1<==>2<==>3

开始添加静态路由

先配置R1

<R1>sy
Enter system view, return user view with Ctrl+Z.
[R1]ip rout	
[R1]ip route-s	
[R1]ip route-static 192.168.3.0 255.255.255.0 192.168.2.10
[R1]dis ip rou	
[R1]dis ip routing-table 192.168.3.10
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Table : Public
Summary Count : 1
Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

    192.168.3.0/24  Static  60   0          RD   192.168.2.10    GigabitEthernet
0/0/1

同理配置R2

[R2]ip route-static 192.168.1.1 255.255.255.0 192.168.2.1
[R2]display ip routing-table 192.168.1.1
Route Flags: R - relay, D - download to fib
------------------------------------------------------------------------------
Routing Table : Public
Summary Count : 1
Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

    192.168.1.0/24  Static  60   0          RD   192.168.2.1     GigabitEthernet
0/0/0

现在就可以互相通信了
