RIP-LAB

学习目的：

学习并掌握RIP在网络环境中的配置方法及特性。

实施拓扑：

R1与R2互连地址段为12.1.1.0/24；

R1-S1/0接口IP地址为12.1.1.1/24；

R1-loopback0环回口IP地址为1.1.1.1/24；

R2-S1/1接口IP地址为12.1.1.2/24；

R2-loopback0环回口IP地址为2.2.2.2/24；

 

 基础配置：

R1
interface Loopback0
 ip address 1.1.1.1 255.255.255.0
!
interface Serial1/0
 ip address 12.1.1.1 255.255.255.0
 no shutdown

R2
interface Loopback0
 ip address 2.2.2.2 255.255.255.0
!
interface Serial1/1
 ip address 12.1.1.2 255.255.255.0
 no shutdown

 

实验步骤：

R1
router rip #设置路由协议为RIP
 version 2 #由于RIP V1为有类路由协议，不支持非连续子网，以广播方式发送报文，协议报文无法携带掩码信息；RIV V2为无类别路由协议，报文中携带掩码信息，支持VLSM&CIDR，以组播的方式发送报文（组播地址为224.0.0.9）。
 network 1.0.0.0 #宣告网络地址段
 network 12.0.0.0
 no auto-summary #关闭路由协议的自动汇总功能

R2
router rip
 version 2
 network 2.0.0.0
 network 12.0.0.0
 no auto-summary

 

结果验证：

R1#show ip route #查看路由信息。
Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route

Gateway of last resort is not set

     1.0.0.0/24 is subnetted, 1 subnets
C       1.1.1.0 is directly connected, Loopback0
     2.0.0.0/24 is subnetted, 1 subnets
R       2.2.2.0 [120/1] via 12.1.1.2, 00:00:07, Serial1/0
     12.0.0.0/24 is subnetted, 1 subnets
C       12.1.1.0 is directly connected, Serial1/0

R1#show ip route rip #只查看通过RIP学习到的动态路由条目。
  2.0.0.0/24 is subnetted, 1 subnets
R 2.2.2.0 [120/1] via 12.1.1.2, 00:00:08, Serial1/0

打"R"，指通过RIP路由协议学习到的动态路由。
【120/1】其中，120为RIP路由协议的管理距离值；1为跳数。
via 12.1.1.2 为下一跳地址，Serial1/0为出接口。

R2#show ip route

R1#ping 2.2.2.2 source 1.1.1.1 #R1通过环回口为源地址为1.1.1.1去PING测试R2的环回口，反之亦然。
