CCNA学习笔记25--RIPv2实验（实验)

实验目的：学习RIPv2的实验配置
实验拓扑：

实验步骤
1.基本配置
2.配置端口ip
3.配置RIPv2
R1(config)#router rip
R1(config-router)#version 2         //运行RIPv2
R1(config-router)#no auto-summary    //关闭RIP的自动汇总，RIP协议是默认自动汇总的，如果不关闭的话，RIP会在主类边界自动汇总到主类
R1(config-router)#network 11.0.0.0
R1(config-router)#network 12.0.0.0

R2(config)#router  rip
R2(config-router)#version 2
R2(config-router)#no auto-summary
R2(config-router)#network 22.0.0.0
R2(config-router)#network 12.0.0.0
R2(config-router)#network 23.0.0.0

R3(config)#router rip
R3(config-router)#version 2
R3(config-router)#no auto-summary
R3(config-router)#network 33.0.0.0
R3(config-router)#network 23.0.0.0
4.验证
R1#show ip route
C        11.1.1.0/24 is directly connected, Loopback0
L        11.1.1.1/32 is directly connected, Loopback0
      12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
C        12.1.1.0/24 is directly connected, Ethernet0/0
L        12.1.1.1/32 is directly connected, Ethernet0/0
      22.0.0.0/24 is subnetted, 1 subnets
R        22.1.1.0 [120/1] via 12.1.1.2, 00:00:06, Ethernet0/0
      23.0.0.0/24 is subnetted, 1 subnets
R        23.1.1.0 [120/1] via 12.1.1.2, 00:00:06, Ethernet0/0
      33.0.0.0/24 is subnetted, 1 subnets
R        33.1.1.0 [120/2] via 12.1.1.2, 00:00:06, Ethernet0/0
R1#ping 33.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 33.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
R1#ping 22.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 22.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
拓展：
R1#show ip protocols
*** IP Routing is NSF aware ***
Routing Protocol is "application"
  Sending updates every 0 seconds
  Invalid after 0 seconds, hold down 0, flushed after 0      //正常来说应该有时间显示，为什么没有呢
  Outgoing update filter list for all interfaces is not set
  Incoming update filter list for all interfaces is not set
  Maximum path: 32
  Routing for Networks:
  Routing Information Sources:
    Gateway         Distance      Last Update
  Distance: (default is 4)
Routing Protocol is "rip"
  Outgoing update filter list for all interfaces is not set
  Incoming update filter list for all interfaces is not set
  Sending updates every 30 seconds, next due in 17 seconds
  Invalid after 180 seconds, hold down 180, flushed after 240
  Redistributing: rip
  Default version control: send version 2, receive version 2
    Interface             Send  Recv  Triggered RIP  Key-chain
    Ethernet0/0           2     2                                   
    Loopback0             2     2                                   
  Automatic network summarization is not in effect
  Maximum path: 4
  Routing for Networks:
    11.0.0.0
    12.0.0.0
  Routing Information Sources:
    Gateway         Distance      Last Update
    12.1.1.2             120      00:00:08
  Distance: (default is 120)
