RIPv2验证

RIPv2验证

在R1,R2上进行配置

 

R1
conf t
int l 0
ip ad 4.4.4.4 255.255.255.255
int s 0
ip ad 10.1.1.1 255.255.255.0
clock rate 64000
ip rip authentication key-chain RIP_authen       在接口上进行验证
ip rip authentication mode md5                        定义验证方法（md5/text）
no shut
exit
key chain RIP_authen           定义key chain的名字
key 1                                     定义key的标识符 
key-string pass                      定义验证码
router rip
ver 2
no au
net 4.0.0.0
net 10.0.0.0

no shut
ip authentication key-chain RIP_authen
ip authentication mode md5
exit
key chain RIP_authen
key 1
key-string pass
router rip
ver 2

R1#ping 5.5.5.5

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 5.5.5.5, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 60/60/60 ms

r2#ping 4.4.4.4

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 4.4.4.4, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 60/61/64 ms
