Stub区域是一种可选的配置属性,但并不是每个区域都符合配置的条件。通常来说,Stub区域位于自治系统的边界,是那些只有一个ABR的非骨干区域。 为保证到自治系统外的路由依旧可达,该区域的ABR将生成一条缺省路由,并发布给Stub区域中的其他非ABR路由器。 配置Stub区域时需要注意下列几点: 骨干区域不能配置成Stub区域。 如果要将一个区
这种情况下,就产生了OSPF的Stub区域。 对于Area 2中的路由器来说,其实区域间的明细路由也没必要都了解,仅保留一个出口让Area 2中的路由器的数据包能够出去就足够了,这就产生了OSPF的Totally Stub区域。Totally Stub区域中,既不允许自治系统外部的路由在区域内传播,也不允许区域间路由在区域内传播,这样就进一步减少...
