1、网络拓扑图
2、二者区别
Stub区域，又称为末梢区域，通常用于自治系统的边界。
特点：
1.不允许4、5类LSA进入该区域，区域内LSDB只存在1、2、3类LSA。
2.可以传递域间明细路由（3类LSA）。
3.ABR会自动下发一条3类LSA的缺省路由。
4.不能引入外部路由。
5.Stub区域内所有的路由器都需要使能Stub特性。
Totally Stub区域：又称为完全末梢区域。
特点：
1.不允许3、4、5类LSA进入该区域，区域内LSDB只存在1、2、3类LSA。
2.不能传递域间明细路由（3类LSA）。
3.ABR会自动下发一条3类LSA的缺省路由。
4.同样不能引入外部路由。
5.Totally stub区域内所有的路由器都需要使能Totally stub特性。
