eigrp md5验证

                                                    EIGRP MD5验证

 

 

 

                         

             两台路由器上

             r1的ip地址是12.12.12.1 255.255.255.0

              r2的ip地址是12.12.12.2 255.255.255.0

               然后分别在两台路由器上配置eigrp

             然后分别在r1上：

R1(config)#key cha
R1(config)#key chain ccnp
R1(config-keychain)#key 1
R1(config-keychain-key)#key
R1(config-keychain-key)#key-string cisco

R1(config)#int e0/0
R1(config-if)#ip authentication mode eigrp 111 md5

R1(config-if)#ip authentication key-chain eigrp 111 ccnp

当敲完这以后路由会down掉

这时候在r2上

R2(config)#key cha
R2(config)#key chain ccnp
R2(config-keychain)#key 1
R2(config-keychain-key)#key
R2(config-keychain-key)#key-string cisco

R2(config)#int e0/0
R2(config-if)#ip authentication mode eigrp 111 md5

R2(config-if)#ip authentication key-chain eigrp 111 ccnp

   eigrp的md5验证完毕~~！！
