OSPF区域验证area area-id authentication

OSPF区域验证area area-id authentication

 

配置简单AREA验证

step1 接口下配置 验证所需的KEY

           ip ospf authentication-key cisco

ip ospf message-digest-key 1 md5 ciscoac   //启用MD5 KEY

step2    在OSPF进程下开启验证

router ospf 1 

             area 0 authentication //启用简单验证

area 0 authentication message-digest   //启用MD5加密验证

setp3      查看验证是否开启

                show ip ospf  

rtrA#show ip ospf
