OSPF区域认证和链路认证 链路认证【链路两端】 AR1: interface g0/0/0 ospf authentication-mode md5 1 cipher huawei

AR2: interface g0/0/0 ospf authentication-mode md5 1 cipher huawei

区域认证【区域内所有】 AR3: area 0.0.0.2 authentication-mode md5 1 plain 123

AR4: ospf 1 router-id 44.44.44.44 area 0.0.0.2 authentication-mode md5 1 plain 123 实验总结： 在ABR上做abr域间路由汇总，在ASBR上做asbr 汇总外部路由。
