若发现了有OSPF邻居,则建立OSPF邻居关系,邻居有两个状态邻居Neighbors及邻接Adjacency。两者间的关系是邻居不一定是邻接,邻接一定是邻居,只有交互了LSA的OSPF邻居才成为OSPF的邻接,之交互Hello包的支撑位邻居,在点对点网络中,所有邻居都能成为邻接;MA(广播多路访问网络,比如以太网)网络类型中,DR,BDR,DRothers三者关系为...
OSPF STUB区域是一个末梢区域，当一个OSPF区域处于整个自治系统边界时，而又不含其他路由协议，这时就可以配置OSPF Stub区域。当配置OSPF Stub区域后，Stub区域中的路由器会增加一条至ABR的默认路由条目，当在ABR上配置了完全末梢区域后，末梢区域的其他路由器的路由条目除了直连的路由条目外，只有一条到达ABR的路由条目...

2. 将area1配置为Stub区域，观察路由及LSA的变化R1的OSPF配置修改如下：[AR1]ospf 1[AR1-ospf-1]area 1[AR1-ospf-1-area-0.0.0.1]stub[AR2]ospf 1[AR2-ospf-1]area 1[AR2-ospf-1-area-0.0.0.1]stub注意，一旦将某个区域设置为Stub，则所有连接到这个区域的路由器都要配置该区域为Stub，否则...
OSPF的master和slave各自的作用是什么 ospf中stub,我们先来看一段经典陈词: stubarea只拒绝外部路由进入,对于区域间路由允许进入 totallyarea不但拒绝外部路由进入,还拒绝区域间路由进入对于区域间访问外部的情况,ABR会向区域内下发一条type3的
ospf 1 area 0.0.0.0 network 192.168.1.0 0.0.0.255 area 0.0.0.1 network 192.168.2.0 0.0.0.255 stub # Return 六、AR3的主要配置: # sysname AR3 # router id 3.3.3.3 # interface GigabitEthernet0/0/0 ip address 192.168.2.2 255.255.255.0 ...
So the primary treatment of point-to-point links in OSPF is to consider them as IP Unnumbered. If they are not IP Unnumbered, OSPF will add an additional stub network record into the LSA-1. In fact, the LSA-1 has no other way of carrying a subnet/mask information! The only link ty...
External routes are not transmitted in the stub area. Virtual links cannot exist in the stub area. Pre-configuration Tasks Before configuring OSPF stub areas, complete the following tasks: Configuring IP addresses for interfaces to ensure that neighboring nodes are reachable at the network layer ...
