RIP路由器协议(RIP路由信息协议

---

一、接口配置

AR1

interface GigabitEthernet0/0/0
ip address 12.1.1.1 255.255.255.0
interface LoopBack0
ip address 1.1.1.1 255.255.255.255

---

AR2

interface GigabitEthernet0/0/0
ip address 12.1.1.2 255.255.255.0
interface GigabitEthernet0/0/1
ip address 23.1.1.2 255.255.255.0
interface LoopBack0
ip address 2.2.2.2 255.255.255.255

---

AR3

interface GigabitEthernet0/0/0
ip address 23.1.1.3 255.255.255.0
interface GigabitEthernet0/0/1
ip address 34.1.1.3 255.255.255.0
interface LoopBack0
ip address 3.3.3.3 255.255.255.0

---

AR4

interface GigabitEthernet0/0/0
ip address 34.1.1.4 255.255.255.0
interface LoopBack0
ip address 4.4.4.4 255.255.255.255

二、RIP配置

AR1

rip 1
network 1.0.0.0
network 12.0.0.0

---

AR2

rip 1
network 12.0.0.0
network 23.0.0.0
network 2.0.0.0

---

AR3

rip 1
network 23.0.0.0
network 34.0.0.0
network 3.0.0.0

---

AR4

rip 1
network 34.0.0.0
network 4.0.0.0

三、实现验证（挑选一个路由器，其他的类似查看）

查看路由表看是否学到路由

---

查看RIP路由表

四、抓包分析

RIP每30S进行一个路由更新

---

使用UDP协议，端口为520

---

协议包解析

---

V1和V2的区别

V1目的地址为广播地址,V2目的地址为组播地址

---

RIP的毒化机制

将自身有的路由器跳数设置成最大16
