我要评论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
