RIP基本配置

RIP（Routing Inormation Protocol）是应用最早的内部网关协议，适合小型网络，是典型的距离矢量路由协议。目前，RIP协议有RIPv1和RIPv2版本，版本1是有类路由协议，版本2是无类路由协议。

【实验目的】

.熟悉动态网络拓扑结构；

.部署RIPv1的动态路由协议；

.理解RIPv1协议的工作原理；

.掌握RIPv1协议的各种配置及查看命令；

.掌握RIPv1协议的相关参数的修改方法；

三、查看路由表

R1路由表
[AR1]display  ip routing-table  
Destinations : 25       Routes : 26
Destination/Mask   Proto   Pre Cost        NextHop         Interface
192.168.1.0/32     Direct  0   0           192.168.1.1     Loop0

192.168.12.0/24    RIP     100 1           192.168.13.1    Ser2/0

四、查看RIP信息

查看rip协议
 
[R1]display  rip
  Public VPN-instance name:
    RIP process: 1
       RIP version: 1
       Preference: 100
       Checkzero: Enabled
       Default cost: 0
       Summary: Enabled
       Host routes: Enabled
       Maximum number of load balanced routes: 32
       Update time   :   30 secs  Timeout time         :  180 secs
       Suppress time :  120 secs  Garbage-collect time :  120 secs
       Update output delay:   20(ms)  Output count:    3
       TRIP retransmit time:    5(s)  Retransmit count: 36
       Graceful-restart interval:   60 secs
       Triggered Interval : 5 50 200
       BFD: Disabled
       Silent interfaces: None
       Default routes: Disabled
       Verify-source: Enabled
       Networks:

           192.168.13.0       
       Configured peers: None

五、查看RIP数据库

[R1]display rip 1 database 
   192.168.1.0/24, auto-summary
   192.168.1.0/24, cost 0, nexthop 192.168.1.1, RIP-interface
   192.168.2.0/24, auto-summary
   192.168.2.0/24, cost 1, nexthop 192.168.12.2
   192.168.3.0/24, auto-summary
   192.168.3.0/24, cost 1, nexthop 192.168.13.3
   192.168.12.0/24, auto-summary
   192.168.12.0/24, cost 0, nexthop 192.168.12.1, RIP-interface
   192.168.13.0/24, auto-summary
   192.168.13.0/24, cost 0, nexthop 192.168.13.1, RIP-interface
   192.168.23.0/24, auto-summary
   192.168.23.0/24, cost 1, nexthop 192.168.12.2
   192.168.23.0/24, cost 1, nexthop 192.168.13.3

六、其他RIP命令

<R1>reset rip 1 process  //重启进程
 
<R1>display  rip 1 interface  Serial 1/0 //查看接口信息
 
<R1>display rip 1 route //查看指定rip进程的路由信息以及每条路由相关的定时器的值
 
[R1-rip-1]preference 120 //设置优先级默认为100
 
[R1-rip-1]timers ? //调整4个定时器的值
  garbage-collect  Garbage-collect timer
  suppress         Suppress timer
  timeout          Timeout timer
  update           Update timer
