路由类型：
直连路由
非直连
静态
动态
IGP：Internal gateway protocol ,内部网关协议
目的：
在内网，快速，计算出一个去往目标网络的，无环，最短，
数据转发路径；
DV-distance vector ，距离矢量路由协议
RIP
IGRP
EIGRP
LS-link state ，链路状态路由协议
ISIS
OSPF
EGP: external gateway protocol ,外部网关协议
目的：
在网络之间，通过BGP实现路由的灵活控制和选路，同时确保
无环；
BGP

RIP 协议配置命令：

1、配置终端设备 - PC1/2

2、配置网络设备
R1/R2/R3/R4
router rip  // 启用路由协议 RIP
version 2  // 配置路由器使用 RIP 版本2
no auto-summary // 关闭 RIP 协议的自动汇总
network 192.168.10.0
network 192.168.12.0  // 以上两个network表示的是
宣告网络 192.168.10.0
192.168.12.0 进入 RIP 协议；

3、验证、测试、保存
show ip protocols //显示当前设备上正在使用的所有路由协议

show ip route // 显示路由表

PC1/2:
ping 192.168.20.1

R1/R2/R3/R4 :
Route#write

在IGP协议中， network 的作用：
# network  10.0.0.0 ， 10.0.0.0 表示的是一个“网络范围”
&在设备上凡是被 10.0.0.0 表示的范围所覆盖住的接口，都启用
路由协议进程：
1、可以在该端口上发送协议报文；
2、可以在该端口上接收协议报文；
3、可以将该端口上的IP地址中的网络部分，放入协议报文中；

interface gi0/1 -> 192.168.34.4 255.255.255.0
interface gi0/2 -> 192.168.20.254 255.255.255.0
interface loopback 0 -> 10.10.4.4 255.255.255.0
#发包
#收包
#10.10.4.0/24 --> RIP --> 发出去；
router rip
network 10.10.4.0 255.255.255.0

==================================================================

RIP
-定义：
routing information protocol , 路由信息协议
在内网的多个路由器之间自动的学习、同步路由表，
以计算出一个去往目标网络的最短、无环、数据转发路径；
-场景：
一般在小规模的企业内部网络使用
(因为RIP有最大跳数限制，最大为 16 跳)
-版本：
version 1
#属于有类路由选择协议(报文不携带子网掩码)
#广播的发送方式 - 255.255.255.255
#无法关闭自动汇总
version 2
#属于无类路由选择协议(报文携带子网掩码)
#组播的发送方式 - 224.0.0.9
#多了一个路由标记(tag)字段，可以实现路由的批量管理；
#多了一个认证功能(使用的是RIP respone报文的第一个路由条目来充当)
#多了一个 mask 字段，从而可以支持关闭自动汇总；
#多了一个 next-hop 字段，从而可以解决“MA网络中的”次优路径问题；

-报文：
request:请求，用于向其他RIP路由器请求更新条目；
respone:响应，用于向其他RIP路由器发送更新条目；是对request的回应
-工作表：
(RIP邻居表)：
#凡是能与自己互通的路由器，都称之为 RIP 邻居；
RIP数据库:
#本地宣告的路由条目
#从其他路由器学习过来的路由条目
RIP路由表：
#表示的是从数据库中挑选出来的最好的路由；
-原理：
1、路由器启用RIP以后，会将自己本地路由表中的条目进行宣告进入到RIP
2、在启动RIP协议的端口上发送这些更新条目；
3、对方RIP路由器接收以后，经过路由比较，将最好的条目放入路由表；
4、所有的RIP路由器都会进行周期性、全部路由表更新，以广播的方式；
（在RIPv2中，是触发式、增量更新，并且是以组播的方式）
-配置
目前网络中凡是使用 RIP 的网络，均使用的 RIPv2 ；
#思科
router rip
version 2
no auto-summary
network x.x.x.x (x.x.x.x必须是主类网络的形式)
#华为
[Router]rip [id] // 如果不写后面的id，默认是1；
[Router-rip-1]version 2 // 在华为中，启用RIPv2以后，默认关闭了自动汇总；
[Router-rip-1]network x.x.x.x
-验证
show ip protocols //查看目前正在运行的所有的路由协议；
show ip rip database // 查看RIP的数据库
show ip route rip //仅仅查看路由表中的 RIP 路由；
show ip route      //查看路由表；

display rip [id]
display rip {id} neighbor // 查看 rip id 的 邻居表；
display rip {id} database // 查看 rip id 的 数据库；
display rip {id} route // 查看 rip id 的路由表；
display ip routing-table

案例：

1 案例1：RIP路由协议原理
1.1 问题
1）动态路由协议的分类有哪些？

2）RIP路由协议的最大跳数是什么？

3）简述水平分割的作用

1.2 步骤
实现此案例需要按照如下步骤进行。

内部和外部网关协议
内部网关路由协议（IGP）：RIP、OSPF、IS-IS
外部网关路由协议（EGP）：BGP
距离矢量和链路状态路由协议
距离矢量路由协议：依据从源网络到目标网络所经过的路由器的个数选择路由，例如RIP、IGRP

链路状态路由协议：综合考虑从源网络到目标网络的各条路径的情况选择路由，例如OSPF、IS-IS

从一个接口学习到路由信息，不再从这个接口发送出去
同时也能减少路由更新信息占用的链路带宽资源
2 案例2：配置RIP路由协议
2.1 问题
1）配置RIP协议实现网络互通

2）查看路由表，验证网络和RIP协议正常

2.2 方案
使用eNSP搭建实验环境，如图-1所示。

2.3 步骤
实现此案例需要按照如下步骤进行。

步骤一：配置RIP路由协议

1）分别配置RIP v1和v2

2）查看路由表，验证网络通信是否正常

4.2 方案
使用Cisco Packet Tracer 搭建实验环境，如图-3所示。

end
2）查看路由表，验证网络通信是否正常
