题目：

一、合理规划IP

192.168.1.0/24分给三个路由器借2位

192.168.1.0/26--骨干

192.168.1.64/26--骨干

192.168.1.128/26 R1（再划分为2个环回接口的ip，借1位）

192.168.1.128/27 192.168.1.160/27

192.168.1.192/26 R2

192.168.1.192/27 192.168.1.224/27

二、配置IP

R1路由器

[r1-GigabitEthernet0/0/0]ip address 192.168.1.1 26

[r1]interface LoopBack 0

[r1-LoopBack0]ip address 192.168.1.128 27

[r1-LoopBack0]ip address 192.168.1.129 27

[r1-LoopBack0]int loo1

[r1-LoopBack1]ip address 192.168.1.161 27

避免环路:[r1]ip route-static 192.168.1.28 26 NULL 0

R2路由器

[R2-GigabitEthernet0/0/0]ip add 192.168.1.2 26

[R2-GigabitEthernet0/0/0]int g0/0/1

[R2-GigabitEthernet0/0/1]ip add 192.168.1.65 26

[R2]interface LoopBack 0

[R2-LoopBack0]ip add 192.168.1.193 27

[R2-LoopBack0]int LoopBack 1

[R2-LoopBack1]ip add 192.168.1.225 27

避免环路：[r2]ip route-static 192.168.1.192 26 NULL 0

R3路由器

[r3]interface LoopBack 0

[r3-LoopBack0]ip address 3.3.3.3 24

[r3-LoopBack0]int g0/0/0

[r3-GigabitEthernet0/0/0]ip add 192.168.1.66 26

三、RIP的配置

1.rip版本选择2和宣告

[r1]rip
[r1-rip-1]vers 2
[r1-rip-1]net	
[r1-rip-1]network 192.168.1.0

[r2]rip
[r2-rip-1]vers 2
[r2-rip-1]net	
[r2-rip-1]network 192.168.1.0

[r3]rip
[r3-rip-1]vers 2
[r3-rip-1]net	
[r3-rip-1]network 192.168.1.0

2.要求3.3.3.0不宣告，在R3（边界路由）上用缺省路由实现

缺省路由 --边界路由器（连接ISP的路由器）上定义缺省源头信息后，将自动向内网发布通告，使得内部所有路由器自动产生缺省路由指向边界路由器；若边界路由器需要缺省路由指向ISP，只能静态手工添加；

[r3]rip
[r3-rip-1]def	
[r3-rip-1]default-route or	
[r3-rip-1]default-route originate

R3添加了缺省路由后R1和R2都会自动添加缺省路由

全网可达已实现

3.路由表汇总

[r1]int g0/0/0
[r1-GigabitEthernet0/0/0]rip summary-address 192.168.1.128 255.255.255.192

[r2]int	
[r2]interface g	
[r2]interface GigabitEthernet 0/0/0
[r2-GigabitEthernet0/0/0]rip su	
[r2-GigabitEthernet0/0/0]rip summary-address 192.168.1.192 255.255.255.192
[r2-GigabitEthernet0/0/0]int g0/0/1
[r2-GigabitEthernet0/0/1]rip summary-address 192.168.1.192 255.255.255.192

4.保障更新安全，注：邻居的间秘钥必须完整一致；

[r1]interface g0/0/0
[r1-GigabitEthernet0/0/0]rip auth	
[r1-GigabitEthernet0/0/0]rip authentication-mode md5	
[r1-GigabitEthernet0/0/0]rip authentication-mode md5 u	
[r1-GigabitEthernet0/0/0]rip authentication-mode md5 usual 2002

[r2]int	
[r2]interface g0/0/0
[r2-GigabitEthernet0/0/0]rip au	
[r2-GigabitEthernet0/0/0]rip authentication-mode md	
[r2-GigabitEthernet0/0/0]rip authentication-mode md5 u	
[r2-GigabitEthernet0/0/0]rip authentication-mode md5 usual 2002
[r2-GigabitEthernet0/0/0]int	
[r2-GigabitEthernet0/0/0]int g	
[r2-GigabitEthernet0/0/0]int g0/0/1
[r2-GigabitEthernet0/0/1]rip authentication-mode md5 usual 1009

[r3]int g0/0/0
[r3-GigabitEthernet0/0/0]rip au	
[r3-GigabitEthernet0/0/0]rip authentication-mode md	
[r3-GigabitEthernet0/0/0]rip authentication-mode md5 u	
[r3-GigabitEthernet0/0/0]rip authentication-mode md5 usual 1009

5.加快收敛速度

-RIP 计时器 30s更新时间 180s失效时间 180s抑制时间 300s刷新
通告改小设备的计时器可以适当的加快协议收敛速度；修改时建议维持原有的倍数关系；且不易修改的过小；
注：一旦修改全网设备需要一致

[r1]rip
[r1-rip-1]ti	
[r1-rip-1]timers r
[r1-rip-1]timers rip 15 90 150

[r2]rip
[r2-rip-1]ti	
[r2-rip-1]timers r	
[r2-rip-1]timers rip 15 90 150

[r3]rip
[r3-rip-1]ti	
[r3-rip-1]timers  r	
[r3-rip-1]timers  rip 15 90 150
