RIP动态路由协议配置实验

项目背景

规划与配置接口 IP地址

AR1：

[AR1-GigabitEthernet0/0/0]ip address 20.0.1.1 24
[AR1-GigabitEthernet0/0/1]ip address 10.0.1.1 24

AR2:

[AR2-GigabitEthernet0/0/0]ip address 20.0.1.2 24
[AR2-GigabitEthernet0/0/1]ip address 20.0.2.1 24

AR3

[AR3-GigabitEthernet0/0/0]ip address 20.0.2.2 24
[AR3-GigabitEthernet0/0/1]ip address 10.0.2.1 24

配置loopback 地址

LoopBack0                         192.168.1.1/24       up         up(s)     
LoopBack1                         192.168.2.1/24       up         up(s)     
LoopBack2                         192.168.3.1/24       up         up(s)

各设备配置 RIP 宣告

AR1:

 network 20.0.0.0
 network 10.0.0.0

AR2:

 network 20.0.0.0
 network 10.0.0.0

AR3:

 network 20.0.0.0
 network 10.0.0.0

在各设备开启V2 版本，默认是 版本1

[AR1-rip-2]version 2

在各设备上查看RIP 路由表项，检查是否学习到了。

dis ip routing-table protocol rip 

Route Flags: R - relay, D - download to fib
Public routing table : RIP
         Destinations : 2        Routes : 2        
RIP routing table status : <Active>
         Destinations : 2        Routes : 2
Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

10.0.2.0/24  RIP     100  2           D   20.0.1.2        GigabitEthernet 0/0/0
20.0.2.0/24  RIP     100  1           D   20.0.1.2        GigabitEthernet 0/0/0

RIP routing table status : <Inactive>
         Destinations : 0        Routes : 0

PC1 PING PC2测试连通性

PC>ping 10.0.1.2

Ping 10.0.1.2: 32 data bytes, Press Ctrl_C to break
From 10.0.1.2: bytes=32 seq=1 ttl=125 time=15 ms
From 10.0.1.2: bytes=32 seq=2 ttl=125 time=32 ms
From 10.0.1.2: bytes=32 seq=3 ttl=125 time=31 ms
From 10.0.1.2: bytes=32 seq=4 ttl=125 time=16 ms
From 10.0.1.2: bytes=32 seq=5 ttl=125 time=31 ms

--- 10.0.1.2 ping statistics ---
  5 packet(s) transmitted
  5 packet(s) received
  0.00% packet loss
  round-trip min/avg/max = 15/25/32 ms

在AR1 RIP视图引入loopback 地址

[AR1]rip 2
[AR1-rip-2]import-route direct 

各设备查看RIP路由表后，发现引入后路由表条目比较多，下面在AR1 接口上做手动聚合

[AR1-GigabitEthernet0/0/0]rip summary-address 192.168.0.0 255.255.252.0

在AR2查看路由表，手工聚合成功

[AR2]dis ip routing-table protocol rip 
Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

       10.0.1.0/24  RIP     100  1           D   20.0.1.1        GigabitEthernet 0/0/0
       10.0.2.0/24  RIP     100  1           D   20.0.2.2        GigabitEthernet 0/0/1
    192.168.0.0/22  RIP     100  1           D   20.0.1.1        GigabitEthernet 0/0/0

在AR1出口加开销值

[AR1-GigabitEthernet0/0/0]rip metricout 5
//如果需要配置入口则配置命令为：metricin//

查看AR2 路由表，发现开销发生变化

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

10.0.1.0/24  RIP     100  5           D   20.0.1.1         GigabitEthernet0/0/0
10.0.2.0/24  RIP     100  1           D   20.0.2.2         GigabitEthernet0/0/1
192.168.0.0/22  RIP     100  5           D   20.0.1.1      GigabitEthernet0/0/0

在AR1上更改优先级

[AR1]rip 2
[AR1-rip-2]preference 10

查表验证,本地RIP 优先级已经改变

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

       10.0.2.0/24  RIP     10   7           D   20.0.1.2        GigabitEthernet0/0/0
       20.0.2.0/24  RIP     10   6           D   20.0.1.2        GigabitEthernet0/0/0

在AR2上做认证

[Huawei-GigabitEthernet0/0/1]rip authentication-mode simple huawei

等待一会，在AR3上查看路由表,发现没有学习到RIP 路由。

Destination/Mask    Proto   Pre  Cost      Flags NextHop         Interface

       10.0.2.0/24  Direct  0    0           D   10.0.2.1        GigabitEthernet 0/0/1
       10.0.2.1/32  Direct  0    0           D   127.0.0.1       GigabitEthernet0/0/1
     10.0.2.255/32  Direct  0    0           D   127.0.0.1       GigabitEthernet0/0/1
       20.0.2.0/24  Direct  0    0           D   20.0.2.2        GigabitEthernet0/0/0
       20.0.2.2/32  Direct  0    0           D   127.0.0.1       GigabitEthernet0/0/0
     20.0.2.255/32  Direct  0    0           D   127.0.0.1       GigabitEthernet0/0/0
      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
255.255.255.255/32  Direct  0    0           D   127.0.0.1       InLoopBack0

在对端设备配置相同命令，即可学习到RIP 路由。

抑制RIP报文在接口上的发送

[AR1-rip-2]silent-interface g0/0/1 //静默接口 只接受 不发送报文
