H3C RIP基本配置实验
实验拓扑

实验需求
- 依据图解完成 IP 地址配置。
- 配置 RIP 网络实现全网路由互通。
- 规定所有网络中 router 必须避免配置明细路由(除了直接连接的 subnet 外),确保网络正常访问。
- 业务 subnet 内禁止存在 protocol 报文。
- R1 和 R2 的 interface 需要启用身份验证机制以确保协议的安全性。
实验步骤
配置 IP 地址
R1

手动路由聚合
要求全网路由器不能出现明细路由(直连网段除外),不影响网络正常访问
明确业务端所在的设备位置,并从该出接口向邻居发送相应的RIP数据包,在该出接口处实施手动路由聚合配置
R1
#
interface GigabitEthernet0/0
rip summary-address 172.16.0.0 255.255.254.0 //路由手动聚合
txt
R3
#
interface GigabitEthernet0/0
rip summary-address 172.16.2.0 255.255.254.0 //路由手动聚合

静默接口,业务网段不允许出现协议报文

身份认证加密
R1 和 R2 之间需要开启接口身份验证来保证协议安全性,密钥为 runtime

interface GigabitEthernet0/0
rip authentication-mode simple plain runtime

R2

实验验证
全网路由互通,且不出现明细路由(直连网段除外)

通过R2查看路由表时发现,在前往PC1和PC2的方向上有两条等价的B类地址;当各台PC之间进行互访时,在这两条等价的路径上发送与接收的数据将同步运行,并由此形成一个回路
环路现象

升级RIP至版本V2后,在最短时间内(不超过180秒)出现故障的路由不再自动更新的情况下,请手动重启RIP进程。
