HCIA整合实验

根据要求，划分如下，整体思路

先将骨干链路作为一个网段，r1、r2、r4、r5的环回个作为一个网段，供需要1+4=5个网段

需向网络位借3位供提供8个网段取前5个，分别是：

192.168.1.0/27---作为骨干链路，再借3位共8个网段取前6个作为骨干链路的网段，如下图

192.168.1.32/27--作为r1的环回，再借1位共2个网段192.168.1.32/28和192.168.1.48/28，如下图

192.168.1.64/27--作为r2的环回，再借1位共2个网段192.168.1.64/28和192.168.1.80/28，如下图

192.168.1.96/27--作为r3的g0/0/2端口的ip，如下图

192.168.1.128/27--作为r4的环回，再借1位共2个网段192.168.1.128/28和192.168.1.144/28，如下图

192.168.1.160/27--作为r5的环回，如下图

192.168.1.160/27--作为r5的环回，如下图

 

首先配置修改每个设备的名称，这里以r1为例

[Huawei]sysname r1

然后给每一路由器配置ip，以r1为例

[r1]interface g0/0/0
[r1-GigabitEthernet0/0/0]ip ad	
[r1-GigabitEthernet0/0/0]ip address 192.168.1.1 30
[r1]interface g0/0/1
[r1-GigabitEthernet0/0/1]ip ad
[r1-GigabitEthernet0/0/1]ip address 192.168.1.5 30

给需要环回接口的路由器配置环回接口，以r1为例

[r1]int	
[r1]interface loo	
[r1]interface LoopBack 0
[r1-LoopBack0]ip ad	
[r1-LoopBack0]ip address 192.168.1.33 28
[r1]int	
[r1]interface loo	
[r1]interface LoopBack 1
[r1-LoopBack1]ip ad
[r1-LoopBack1]ip address 192.168.1.49 28

置完成后，查看路由表，以r1为例：

[r1]display ip interface  brief 
*down: administratively down
^down: standby
(l): loopback
(s): spoofing
The number of interface that is UP in Physical is 5
The number of interface that is DOWN in Physical is 1
The number of interface that is UP in Protocol is 5
The number of interface that is DOWN in Protocol is 1

Interface                         IP Address/Mask      Physical   Protocol  
GigabitEthernet0/0/0              192.168.1.1/30       up         up        
GigabitEthernet0/0/1              192.168.1.5/30       up         up        
GigabitEthernet0/0/2              unassigned           down       down      
LoopBack0                         192.168.1.33/28      up         up(s)     
LoopBack1                         192.168.1.49/28      up         up(s)     
NULL0                             unassigned           up         up(s)    

接着配置静态路由，配置静态路由是，先配置缺省，不符合缺省路线的再添加上，以r1为例

 开启r3的dhcp服务

[r3]dhcp enable 
Info: The operation may take a few seconds. Please wait for a moment.done.
[r3]ip pool aa
Info: It's successful to create an IP address pool.
[r3-ip-pool-aa]netw	
[r3-ip-pool-aa]network 192.168.1.96 ma	
[r3-ip-pool-aa]network 192.168.1.96 mask 27
[r3-ip-pool-aa]gat	
[r3-ip-pool-aa]gateway-list 192.168.1.97
[r3-ip-pool-aa]q
[r3]int	
[r3]interface g0/0/2
[r3-GigabitEthernet0/0/2]dhcp se	
[r3-GigabitEthernet0/0/2]dhcp select g	
[r3-GigabitEthernet0/0/2]dhcp select global

 r1上开启telent服务

[r1]aaa
[r1-aaa]local	
[r1-aaa]local-user admin	
[r1-aaa]local-user admin pr
[r1-aaa]local-user admin privilege level 15 password ci	
[r1-aaa]local-user admin privilege level 15 password cipher 123
[r1-aaa]loca	
[r1-aaa]local-user ad	
[r1-aaa]local-user admin ser	
[r1-aaa]local-user admin service-type tel	
[r1-aaa]local-user admin service-type telnet
[r1]user-interface vty 0 4
[r1-ui-vty0-4]au	
[r1-ui-vty0-4]authentication-mode aaa 

 r5上设置端口映射

[r5]int g0/0/1
[r5-GigabitEthernet0/0/1]nat se	
[r5-GigabitEthernet0/0/1]nat server pr	
[r5-GigabitEthernet0/0/1]nat server protocol tcp	
[r5-GigabitEthernet0/0/1]nat server protocol tcp gl	
[r5-GigabitEthernet0/0/1]nat server protocol tcp global curr	
[r5-GigabitEthernet0/0/1]nat server protocol tcp global current-interface 23 in	

[r5-GigabitEthernet0/0/1]nat server protocol tcp global current-interface 23 ins
ide 192.168.1.1 23
Warning:The port 23 is well-known port. If you continue it may cause function fa
ilure.
Are you sure to continue?[Y/N]:y

 浮动静态路由，r4上

[r4]ip route-static 0.0.0.0 0 192.168.1.22 preference 70
[r4]ip route-static 192.168.1.160 27 192.168.1.20 preference 70
[r4]ip route-static 0.0.0.0 0 GigabitEthernet 0/0/2 192.168.1.18

 r5上

[r5]ip route-static 192.168.1.0 24 192.168.1.21 preference 70

空接口防环路由，以r1为例

[r1]ip route-static 192.168.1.32 27 NULL 0

测试

全网可达，用r1去Ping  r6的环回

<r1>ping 1.1.1.1
  PING 1.1.1.1: 56  data bytes, press CTRL_C to break
    Reply from 1.1.1.1: bytes=56 Sequence=1 ttl=252 time=50 ms
    Reply from 1.1.1.1: bytes=56 Sequence=2 ttl=252 time=40 ms
    Reply from 1.1.1.1: bytes=56 Sequence=3 ttl=252 time=50 ms
    Reply from 1.1.1.1: bytes=56 Sequence=4 ttl=252 time=40 ms

PC1和PC2DHCP服务自动获取IP

pc1

PC>ipconfig

 r6去telent r5时

<r6>telnet 22.0.0.1
  Press CTRL_] to quit telnet mode
  Trying 22.0.0.1 ...
  Connected to 22.0.0.1 ...

Login authentication


Username:admin
Password:
<r1>

将R4到R5的1000M链路关掉，去测试浮动静态

[r4-GigabitEthernet0/0/2]shutdown 

 再去查看r4的路由表

[r4]display ip routing-table 
      0.0.0.0/0   Static  70   0          RD   192.168.1.22    GigabitEthernet
4/0/0

完成所有要求
