H3C OSPF Stub特殊区域+认证实验
实验拓扑
实验需求
- 按照图示配置 IP 地址，所有路由器配置环回口 IP 地址为
X.X.X.X/32 作为 Router-id，X 为设备编号（R5 除外） - 按照图示分区域配置 OSPF
- R1 上配置默认路由，指向 R5，通往外部网络
- Area 1 为了减小路由表规模，配置为 Stub 区域
- R4 上配置环回口模拟业务网段；要求所有业务网段的路由聚合为一条后发布到 Area 0
- R2 上不允许存在
192.168.2.0/24 网段和192.168.3.0/24 网段的路由 - 为了保证协议安全，Area 0 配置区域验证，验证密钥

#
ospf 1 router-id 2.2.2.2

减小路由表规模配置Area1为Stub区域
方法一：Stub区域配置
[R2-ospf-1-area-0.0.0.1]stub
[R3-ospf-1-area-0.0.0.1]stub
[R4-ospf-1-area-0.0.0.1]stub
方法二：Totally Stub区域配置（扩展配置，非需求）
配置说明：Totally Stub区域只需在ABR路由器上配置，普通路由器开启stub即可
[R2-ospf-1-area-0.0.0.1]stub no-summary
[R3-ospf-1-area-0.0.0.1]stub no-summary
[R4-ospf-1-area-0.0.0.1]stub
实验验证
检验Area0配置区域认证后是否能建立OSPF邻居
分别在R1、R2、R3上重置OSPF进程，Area0依然可以建立邻居，区域认证配置正确

ABR上的路由聚合是否聚合成功
在R1上查看路由表，业务网段成功聚合为192.168.0.0/22，由ABR发布给了R1

Area1配置为Stub区域是否减小路由表规模
在R4上查看，发现配置为stub区域后，路由表中的默认路由，由0_ASE2（OSPF第二类外部路由）变为O_INTER（OSPF区域间路由），且查看R4上的LSDB，配置stub区域后无Type5路由，只存在Type1、2、3类型的路由。

扩展：若Area1配置为Totally Stub区域是否再次减小路由表规模
原配置的stub区域，只是将由ASBR发布过来的Type5类路由通过ABR转成Type3类路由传递给R4，但依然存在着其余网段的路由，并不算非常精简的路由表，将之配置成Totally Stub区域后，发现原传递过来的Type3类路由，仅剩余1条缺省路由，这样极大减小了R4的路由表规模。
