EIGRP Authentication验证

一、配置MD5验证(不支持明文验证)

key chain ccnp　           #（本地有效）定义KEY库名为ccnp
key 1                       #（两端一致）定义KEY号为1
key-string cisco           #定义KEY值为cisco

int s1/0
ip authentication mode eigrp 100 md5  #开启认证
ip authentication key-chain eigrp 100 ccnp 

二、基于时间的验证

R2: key chain ccnp
R2: key 1
R2: key-string cisco
R2: accept-lifetime 13:45:00 Feb 3 2015 infinite
R2: send-lifetime 13:45:00 Feb 3 2015 13:55:00 Feb 3 2015
R2: key 2
R2: key-string cisco2
R2: accept-lifetime 13:45:00 Feb 3 2015 infinite
R2: accept-lifetime 13:55:00 Feb 3 2015 infinite

三、查看
